Question

Melanie bought two different pieces of wire to make different types of jewelry. She bought a 16-gauge piece of wire and cut it into six 16.5-inch pieces. She also bought a 22-gauge piece of wire and cut it into eight 9.6-inch pieces. What is the difference in the total lengths of the two wires that Melanie bought?

Answer 1

The length of the 16-gauge wire is 16.5 inches * 6 pieces = 99 inches.

The length of the 22-gauge wire is 9.6 inches * 8 pieces = 76.8 inches.

The difference in the total lengths is 99 inches - 76.8 inches = 22.2 inches.
