The students in a club are selling flowerpots to raise money. Each flowerpot sells for $21. Part A Write an expression that represents the total amount of money, in dollars, the students raise from selling x flowerpots. Enter the expression in the box provided. Enter only your expression.
Answer: y = 21x
Step-by-step explanation:
y in this expression represents the total amount of money, in dollars, the students raise from selling x flowerpots.
21 is the price of each flower pot.
x is the number of flower pots sold.
If for instance, they sold 30 flower pots, y(total amount in dollars) would be;
= 21x
= 21 * 30
= $630

Find the cost price of the following
Selling price: 55$, Profit 10%
Step-by-step explanation:
If cost price = A $
110/100 × A = 55
A = 55 × 100/110
= 50 $
Cost price 50 $
Which value completes the equation?
56,000÷_____ = 800
Answer:
Answer is 70
Step-by-step explanation:
Let's see here. 7 times 8 equals 56 and there's a 56 with 3 zeroes. 70 times 800. 7 times 8 equals 56 then add the 3 zeroes which gives us 56,000 which tells us that 70 is the correct answer.

Bag Ladies, Inc. Manufactures two kinds of bags—totes and satchels. The company allocates manufacturing overhead using a single plantwide rate with direct labor cost as the allocation base. Estimated overhead costs for the year are $25,500. Additional estimated information is given below. Totes Satchels Direct materials cost per unit $33 $40 Direct labor cost per unit $53 $61 Number of units 530 360 Calculate the amount of overhead to be allocated to Totes. (Round any percentages to two decimal places and your final answer to the nearest dollar.)
Answer:
Allocated MOH= $14,312
Step-by-step explanation:
Giving the following information:
Estimated overhead costs for the year are $25,500.
Totes Satchels:
Direct labor cost per unit $53 $61
Number of units 530 360
First, we need to calculate the allocation rate:
Predetermined manufacturing overhead rate= total estimated overhead costs for the period/ total amount of allocation base
Predetermined manufacturing overhead rate= 25,500 / (53*530 + 61*360)
Predetermined manufacturing overhead rate= 25,500/50,050
Predetermined manufacturing overhead rate= $0.5095 per direct labor dollar
Now, we can allocate overhead to Totes:
Allocated MOH= Estimated manufacturing overhead rate* Actual amount of allocation base
Allocated MOH= 0.5095*(53*530)
Allocated MOH= $14,311.855

Find the missing values in each row. Use the percent equation. A: Principal: $100 Interest rate: 5% Time in years: 3 Interest earned: B: Principa;" $500 Interest rate: 4% Time in years: interest earned: $20 C: Principal: Interest rate:10%% Time in years: 7 Interest earned:$35 D: Principal: $200 Interest rate: Time in years:2 Interest earned: $6
Answer:
A.) 15
B.) 1 year
C.) $50
D.) 1.5%
Step-by-step explanation:
The percentage equation goes thus:
Interest earned = principal * rate * time
A)
Principal: $100 Interest rate: 5% Time in years: 3 Interest earned
Interest earned = $100 * 0.05 * 3
Interest earned = $15
B.)
Principa;" $500 Interest rate: 4% Time in years: interest earned: $20
Interest earned = principal * rate * time
20 = 500 * 0.04 * time
20 = 20 * time
Time = 20 / 20 = 1
Time = 1 year
C.)
Principal: Interest rate:10% Time in years: 7 Interest earned:$35
Interest earned = principal * rate * time
$35 = principal * 0.1 * 7
$35 = principal * 0.7
Principal = $35 / 0.7
Principal = $50
D.)
Principal: $200 Interest rate: Time in years:2 Interest earned: $6
Interest earned = principal * rate * time
$6 = $200 * rate * 2
$6 = $400 * rate
Rate = $6/$400
Rate = 0.015 = 1.5%

Work out the equation of the straight line which has a gradient of 2
Note: It seems you may forget to write the complete statement. Maybe you should have either mentioned the y-intercept or any other point to work out the equation.
Anyways I am assuming your complete statement is ''Work out the equation of the straight line which has a gradient of 2 and passes through (1, 4)''.
Answer:
We conclude that the equation of a line using the slope-intercept form is
[tex]y=2x+2[/tex]Step-by-step explanation:
I am assuming your complete statement is ''Work out the equation of the straight line which has a gradient of 2 and passes through (1, 4)''.
The slope-intercept form of the equation
[tex]y=mx+c[/tex]
Here
m is the slopec is the y-interceptSubstituting the point (1, 4) and m=2 to determine the y-intercept
[tex]y=mx+c[/tex]
[tex]4 =2(1)+c[/tex]
[tex]4 = 2+c[/tex]
[tex]c = 4-2[/tex]
[tex]c = 2[/tex]
Thus, the equation of a line using the slope-intercept form is
[tex]y = mx+c[/tex]
m=2c=2[tex]y=2x+2[/tex]
Therefore, we conclude that the equation of a line using the slope-intercept form is
[tex]y=2x+2[/tex]Answer:
you are missing part of your question

When solving equations we always undo the addition or subtraction first.

Answer:
y=3x+3
Step-by-step explanation:
to find the y-int, you need to find the point the is on the y-axis (0,x). Or, 3 in this situation
for slope, you just need to do rise over run, or up and down first then, left and right. If i do that for this equation, I will get 3/1 which is the slope.

Answer:
3 trays of corn muffins and 2 trays of bran muffins
Step-by-step explanation:
c = 4m + 3w
b = 2m + 3w
16m and 15w
1 tray of corn muffins and 4 trays of bran muffins = $11
16 - 4 = 12
15 - 3 = 12
12 - 8 = 4
12 - 12 = 0
b = $2
c = $3
c = 3 x 1 = 3
b = 2 x 4 = 8
3 + 8 = 11
-----------------------------------------------------------------------------------------------------------------
2 trays of corn muffins and 3 trays of bran muffins = $12
c = 4m + 3w
b = 2m + 3w
16 - 8 = 8
15 - 6 = 9
8 - 6 = 2
9 - 9 = 0
b = $2
c = $3
c = 3 x 2 = 6
b = 2 x 3 = 6
6 + 6 = 12
-----------------------------------------------------------------------------------------------------------------
3 trays of corn muffins and 2 trays of bran muffins = $13
c = 4m + 3w
b = 2m + 3w
16 - 12 = 4
15 - 9 = 6
4 - 4 = 0
6 - 6 = 0
c = 3 x 3 = 9
b = 2 x 2 = 4
9 + 4 = 13
-----------------------------------------------------------------------------------------------------------------
4 trays of corn muffins and 0 trays of barn muffins = $12
c = 4m + 3w
b = 2m + 3w
16 - 16 = 0
15 - 12 = 3
c = 3 x 4 = 12
b = 2 x 0 = 0
12 + 0 = 12

Hilda adds 5 to a number, then multiplies the sum by -2. The result is 6. Write an equation to find the number, x. What is the number?
Answer: -8
Step-by-step explanation:
If we add 5 to -8, that will be -3. Then if we multiply -3 with -2, it equals 6 because when two negatives multiply with one another the answer will be positive.
So in conclusion, the number is -8.
Hope this helps!
