Answer:
$136.50
Step-by-step explanation:
100 - 12 = 88% (How much percentage of money the student left)
88% = 120.12
1% = 120.12 ÷ 88 = 1.365
Before buying the book, the student had 100%
100% = 1.365 x 100 = 136.50
Step-by-step explanation:

c² = a² + b²
Making a² subject then
a² = c² - b²
Hope it will help :)
