Question

Robyn saves $204 and spends $32.50 on books. She wants to purchase more books from a sale where they cost $8.15 each.

Which answer gives the best estimate for the number of books Robyn can buy?


88

2121

192192

200

Answer 1

21 books

Explanation:

Subtract $32.50 from her total savings:

$204 - $32.50 = $171.50

Divide the remaining money by the cost for each book from the sale:

$171.50 / $8.15 = 21.0429448

Round:

21 books
