Question

A shirt is on sale for $15. If the shirt was marked down by 10%, then what was the original price

Answer 1

$17

Explanation:

if the shirt was marked down by 10%, percentage for the original price will be(100-10)%= 90%

let the original price for the shirt = X

therefore,

90%--------------$15

100%--------------X

cross multiplying

90×X= 100×15

90X = 1500

dividing bothsides by 90

90X/90 = 1500/90

X = 16.67=$17(approximately)

X= $17
