You work in a hardware store. You have two boxes of nails. The first box weighs 6 pounds, 7 ounces, and the second box weighs 2 pounds, 9 ounces. Which equation can be used to calculate how much the two boxes weigh in
ounces?
O ounces = 16(6 + 2) + 16
O ounces = 16(6 + 2)
O ounces = 16(6 x 2) + 16
O ounces = 16(6 x 2)
O ounces = 16(6+2)
