Question

You go shopping for some new shoes on a sales tax free weekend (yay no taxes!). You have a 20% off coupon. If you have a $100 to spend, what is the maximum price of the shoes you can buy with the coupon? Explain how you figure out your answer.

Answer 1

$125

Explanation:

let the maximum price be 'x'

`x -( (20)/(100) * x) = 100`

`x - ( (x)/(5) ) = 100`

`(4x)/(5) = 100`

`4x = 500`

`x = 125`

BRAINLIEST PLEASE! :-)

Answer 2

$125

Explanation:

With a 20% off coupon, the price you pay is 80% of the marked price. If that amount is $100, you have ...

$100 = 0.80p

p = $100/0.80 = $125

The maximum price of the shoes you can buy is $125.

20% of $125 is -.20×$125 = $25. When that is subtracted, the price you pay is ...

$125 -25 = $100
