Abe is buying taco shells for a party. There will be 13 adults and 17 children attending the party. He plans to make 3 tacos for each adult and 1 taco for each child. There are 8 taco shells in each package. What is the least number of packages of taco shells Abe will need to buy in order to have enough tacos for the people attending the party?

• 7, because (13x3+17) ÷ 8 = 7
• 28, because (13x17+3) ÷ 8=28
• 80, because (13+17) x8 ÷ 3=80
• 8, because (13+17x3) ÷ 8=8
