Tobias is buying a new pair of shoes that costs $95. He has been saving up his money each month for the past three months. He gets a $5 allowance a month. He also mows lawns and shovels driveways. He charges $15 to mow a lawn and $7 to shovel. After buying the shoes, he has $15 in change. If he mows 4 lawns, how many driveways did he shovel? Think carefully first, then make a decision:

He saved up $110 total because 95 + 15 = 110. He saved $15 from his allowance because 3 x 5 = 15. He earned $60 mowing lawns because 4 x 15 = 60. He earned $35 shoveling driveways because 110 - 60 - 15 = 35. He shoveled 5 driveways because 35 / 7 = 5. So, the answer is 5.
