Answer:
$17
Step-by-step 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
