Understanding Propane Cost Function

The video tutorial explains how to determine the cost of filling a motorhome's propane tank using the function C(G) = 3.11G, where G is the number of gallons. It covers calculating the cost for a specific number of gallons, interpreting results as ordered pairs, solving for the number of gallons given a cost, and determining the practical domain and range of the function. The tutorial includes graphing the function and understanding the constraints based on the propane tank's capacity.

What is the function used to determine the cost of filling a propane tank?

• C(G) = 5.11G

• C(G) = 2.11G

• C(G) = 4.11G

• C(G) = 3.11G
