Cassie Marino is interested in purchasing a new laptop computer for school. It is marked down 20% from its original price. She can save a $112.00 by buying the marked down computer. How much was its original price?

$560

$400

$448

$512

Check each number first

Multiply each answer by 20%

$560 * 20% = $112 (or 0.20 divide the % by 100)

$400 * 20% = $80 (or 0.20 divide the % by 100)

$448 * 20% = $89.60 (or 0.20 divide the % by 100)

$512 * 20% = $102.40 (or 0.20 divide the % by 100)

Since $560 * 20% = $112 (What your lookin for)

(I suppose that is $560 is answer choice A)

A is your answer because that is the original price.

Do it as a ration, it's easier like that ...
