Cary is saving money to buy a new pair of shoes that cost $120. He has already saved $30. He earns $5 for every lawn he mows. If he mows 3 lawns each weekend, how many more weekends will he have to mow lawns before he can afford to buy the shoes?
Thoughts? Step-by-step reasoning:
User
Cary needs to save an additional $120 - $30 = $90. Cary makes $5 * 3 = $15 each weekend. It will take 90 / 15 = 6 more weekends to save enough money to afford the shoes.
Thus, the answer is 6.
