Question

Ethan spent 12.5% of the money in his pocket on dinner. His dinner cost $15.25. How much did he have in his pocket? Group of answer choices $102.00 $172.36 $190.63 $122.00

Answer 1

$122

Explanation:

Let total money in his pocket = $ x

12.5% of x = $ 15.25

`(12.5)/(100)*x= 15.25`

Multiply both sides by 100

12.5 *x = 15.25*100

125.5 *x = 1525

Divide both sides by 125.5

`x = (1525)/(12.5)\\\\`

x = $ 122
