Jeremy buys 3 bags of chips for a party. Stacy and Emily also buy chips for the party. If they need 10 bags of chips total, and Stacy buys 4 bags, how many bags of chips should Emily buy?
Jeremy and Stacy buy 3+4 = <<3+4=7>>7 bags of chips.
Since there needs to be 10 total, Emily should buy 10-7=<<10-7=3>>3 bags of chips.
