Solve.A truck rental company rents a moving truck one day by charging $29 plus $0.09 per mile. Write a linear equation that relates the cost C, in dollars, of renting the truck to the number x of miles driven. What is the cost of renting the truck if the truck is driven 130 miles?
A. C = 0.09x - 29; $17.30 B. C = 29x + 0.09; $3770.09 C. C = 0.09x + 29; $40.70 D. C = 0.09x + 29; $30.17
