Question

Mary has $33. She wants to buy a book that cost $53 and will save $5 per week. How many weeks will it take for her to have enough for her book?

Answer 1

4 weeks

Explanation:

if she starts with $33, and she gets $5 per week, and she need $53, then you would add $5 starting at $33 until you reach the book price of $53. Or you could subtract $33 from $53 and then divide that answer by $5.
