A pizza delivery service will pay you $0.50 per mile plus $6.00 per hour. You calculate that it costs you about $0.20 per mile in gas and wear and tear on your car. Choose the expression that best represents how much you will make by delivering pizza.

• (0.50 + 6.00)(H) - 0.20G

• (0.50 - 0.20)(M) + 6.00(H)

• 0.50(M) - 0.20(G) + 6.00

• 0.50(M) + 6.00(H) + 0.20(G)
