Question

Last year the price of a college book was $32. This year the price of the book has increased. The college book's new price is $40. What is the percent increase in the price of the book? (answer must include %)

what we can do is figure out how much 40/32 is when converted into a fraction. 40/32 is 125% when converted. this means the price increased by 25%
