Solve the problem.A convenience store charges $1.10 for a 24 ounce soda and $0.99 every refill. A gas station charges $1.50 for a 24 ounce soda and $0.99 for every refille. Write the cost model equations for both places and find the number of refills that makes the costs equal.

Question

A. Convenience store: y = 0.99x - 1.10
Gas station: y = 0.99x - 1.50
The costs are never equal
B. Convenience store: y = 0.99x + 1.10
Gas station: y = 0.99x + 1.50
5 refills make the costs equal
C. Convenience store: y = 0.99x + 1.10
Gas station: y = 0.99x + 1.50
The costs are never equal
D. Convenience store: y = 1.10x + 0.99 
Gas station: y = 1.50x + 0.99
5 refills make the costs equal
