<human>:  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?
<bot>: How much more money does Cary need to save? ** Cary needs to save an additional $120 - $30 = $<<120-30=90>>90.
How much money does Cary make each weekend? ** Cary makes $5 * 3 = $<<5*3=15>>15 each weekend.
How many more weekends will Cary have to mow lawns before he can afford to buy the shoes? ** It will take 90 / 15 = <<90/15=6>>6 more weekends to save enough money to afford the shoes.
