Question

A store owner paid $15 dollars for a book. she marked up the price of the book by 40% to determine it's selling price.

Answer 1

A) $15 ÷ 40% =
15×.4= 6
15+6= 21

B) $38 × .25=9.5
38-9.5=28.50

28.50×.06=1.71
28.50+1.17=30.21

I think this is how you do it. would wait for other answers as well to double check.

Answer 2

Part A)

$15 ÷ 40% =  15×.4= 6

15+6= 21

Part B) $38 × .25=9.5

38-9.5=28.50

28.50×.06=1.71

28.50+1.17=30.21
