The owner of an audio store received a shipment of portable stereos at a cost of $88.90 each. If he sells the stereos for $152.99 each, what is the percent of markup? Round to the nearest whole percent.

Answers

He would get a profit of 64.09
64.09 or 64% because if you subtract 152.99 from 88.90 you get 64.09 and you round it to 64% because the 0 is under 5 so you lower it

help pls it due today and i.d.k. what to do the one that said mean thats is the understanding o i but i dont understand it

Answers

to find the mean you add up all of the numbers that you see, then divide that total by the numbers you divided. in this case you would add 3+5+7+10+10+4+7+5+8+10+6. you should get 75. you added 11 numbers together so you would divide 75 by 11 to get 6.8
3+5+7+10+10+4+7+5+8+10+6=75

75/11=6.81

you add all the numbers together then you divide the answer by how many numbers you have


i hope this helps

Can somebody please help me out with this. We have to do it point slope form.
[tex]y - y_{1} = m( x - x_{1})[/tex]

Answers

Explanation:

The formula y - y1 = m(x - x1) is usually described as the 'point-slope form' for the equation of a line. It is useful because if you know one point on a certain line and the slope of that certain line, then you can define the line with this type of formula and, thus, find all the other points on that certain line.

Solve the system y = -x + 7 and y = -0.5(x - 3)^2 + 8

Answers

Step-by-step explanation:

-x+7=-0.5(x-3)^2+8

-x+7=-0.5x^10 -4.5^10

am I getting ...!?

Answer:

(-1,6) and (-7,0)

Step-by-step explanation:

-x+7=-0.5(x-3)^2+8

times both sides by -2

2x-14=(x-3)^2-16

expand

2x-14=x^2-6x+9-16

add 14-2x to both sides

0=x^2-8x+7

factor

0=(x-7)(x-1)

set to zero

0=x-7

7=x

0=x-1

1=x

so find y

y=-x+7

y=-1+7

y=6

or

y=-7+7

y=0

2.396 liters
239.6 liters

23,960 liters

Answers

2.396 which is also a.

Answer:

2.396

Step-by-step explanation:

The units of measurement go like this:

Kilo, hecto, deca, unit, deci, centi, mili

When you move to the right, you move the decimal one place to the right, and when you move left, you move the decimal one place to the right

If you’re changing milliliters to liters (unit), you have to more the decimal 3 times to the left. This makes it 2.396 liters
