Muhammad, a shipping and receiving clerk, uses 1 yard, 2 feet, 4 inches of twine to wrap each carton he packs. He has to pack 29

Vsevolod [243]

Answer:

Twine needed to wrap 29 cartons = 51.55 yards

Explanation:

Twine needed to wrap one carton = 1 yard, 2 feet, 4 inches

= 1 + 2 x 0.3333 + 4 x 0.027778

= 1.777712 yards.

Twine needed to wrap 29 cartons = 1.777712 x 29 = 51.55 yards.

Twine needed to wrap 29 cartons = 51.55 yards
