Kendra saw a calculator on sale for $68.25. The original price of the calculator was $89.99.

What is the approximate discount on the calculator?


20%

25%

30%

35%

Answers

The approximate percentage discount is equal to 25%.

Given the following data:

Sales price = $68.25.Original price = 89.99

To calculate the approximate discount on the calculator:

First of all, we would determine the discount on the calculator by using the following mathematical expression:

[tex]Discount = Original\;price -Sales\;price[/tex]

[tex]Discount = 89.99 -68.25[/tex]

Discount = $21.74

Now, we can calculate the approximate percentage discount:

[tex]Percent\;discount = \frac{21.74}{89.99} \times 100\\\\Percent\;discount = \frac{2174}{89.99}\\\\Percent\;discount = 24.16[/tex]

Percent discount = 25%

account. Later that evening, Andrew made online payments of $3.24, $18.30,
$38.96, $100.34, and $314.78. His goal is to keep only a $10 balance in his
checking account and have most of his money in savings. How much money
was available in Andrew's checking account to be transferred to savings after
all the transactions were completed?

Answers

$28.38

1.39 + 512.89= $514.28

3 + 18 + 38 + 100 + 314 = $473

.24 + .30 + .96 + .34 + .78 = $2.62

473 +2.62 = $475.62

514 - 475.62 = $38.38

38.38 - 10 = $28.38

What is an expression?

Expression in mathematics is combination of variables with the use of operations and given rules. It can be in the form of equation, numbers etc.

If x and y are the arbitrary numbers.

And sum of the numbers are x + y,

difference of the numbers are x - y and

quotient of number x and y is x/y.

Here we have the expression and their representation,

the quotient of a number and 12 = p/12

the sum of a number and 12 = p + 12

the difference between 12 and a number =  p - 12.

Therefore the expression in the box for the quotient of a number and 12,

the sum of a number and 12 and the difference between 12 and a number are p/12 , 12 + p and p - 12.

share 5,000 in the ratio of 1:2:3:4​

Answers

Answer:

500 : 1000 : 1500 : 2000

Step-by-step explanation:

sum the parts of the ratio , 1 + 2 + 3 + 4 = 10 parts

Divide the amount by 10 to find the value of one part of the ratio

5000 ÷ 10 = 500 ← value of 1 part of the ratio , then

2 parts = 2 × 500 = 1000

3 parts = 3 × 500 = 1500

4 parts = 4 × 500 = 2000

5000 = 500 : 1000 : 1500 : 2000 in the ratio 1 : 2 : 3 : 4

Total
1:2:3:4 10
500:1000:1500:2000 5000

Steps:

1+2+3+4=10
5000 divided by 10= 500
500x1=500
500x2=1000
500x3=1500
500x4=2000

So the final answer is

500:1000:1500:2000
