Question

PART A:A sporting goods store offers a 40% discount on all golf clubs. Rocco spent 20% of the money in his savings account on a golf putter. He paid $48 for the putter after the discount. How much money did Rocco have in his savings account after buying the putter?

Answer 1

He spent 20% of his savings, and according to the problem, that is $48. So:

20% of x=$48

.20x=48
x=48/.20

x=$240 was in his account, so after spending $48, that would be
240-48
=$192 left in his savings account.
