Math Homework Question (HELP!!!)

Question

John bought a shirt on sale for 25% off the original price, which was then further discounted by 20%. If the final price was $18, what was the price before the first discount?

Answer 1

25% plus 20% off = 45% off with final discounted price = $18

$18 is 55% of the original price

OP = 18/.55 = about $32.73 original price

Unless you meant the 20% was not 20% of the original price, but 20% off the price after the 1st discount

then, the 1st discounted price = 75% of the original price

OP =DP/.75

and the 2nd Discounted price = 80% of the 1st discounted price DP = 2DP/.8 = 18/.8

OP = (18/.8)/.75= $30

odds are you probably want $30 as the original price. It comes out so even.

30 x 25% = 7.5

30-7.5 = 22.5 = 1st discounted price

22.5 x 20% = 4.5

22.5-4.5 = $18
