A car rental company charges a flat fee of $50 plus $0.20 per mile driven. If a customer drives 150 miles, write a standard form equation to calculate the total cost of the rental.

• Total Cost = 50 + (0.20 * 150) = 50 + 20 = 70

• Total Cost = 50 + (0.20 * 150) = 50 + 50 = 100

• Total Cost = 50 + (0.20 * 150) = 50 + 15 = 65

• Total Cost = 50 + (0.20 * 150) = 50 + 30 = 80
