How to calculate percentages

Question

Andrew won a cash prize on a game show. Andrew paid taxes of 30% on the original cash prize and had $28,000 remaining. How much was the original cash prize?

Answer 1

Andrew paid 30% in taxes, which means he has 70% remaining

 

30% Cash Prize + 70% Cash Prize = 100% Cash Prize

 

If C = Original Cash Price

 

Remaining Cash = 70% x C = $28,000

 

C = $28,000 / 70% = 28000/0.7 = $40,000
