Question

David had 80 dollars from washing cars

He did the following with his money

He put 50% of the $80 in his savings account

He paid 25% of the remaining for money he had borrowed

He bought a brand new guitar with the rest of the money

How much did the guitar cost?

Answer 1

It cost 30$

Explanation:

Since 50% is 1/2 we put 80/2

so we have 40

25% is 1/4 we put 40/4=10 40-10=30

so the answer is 30
