The weight W of an aluminum flatboat varies directly with the L length of the boat. If a 11-ft boat weighs 132 pounds, then what is the weight of a 13 ft boat?

Answer 1

I don't know what kind of a School Subject "GCU" is, but to answer your question:

Divide 132 pounds by 11 to determine the weight per foot of flatboat. Then multiply that number by 13 to determine the weight of a 13-foot boat.

Answer 2

156 pounds
