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.
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
