A truck company charges $20 for a one-day truck rental, plus $0.65 per mile. Formulate a linear function to model the cost C(d) of a one-day rental driven d miles, and determine the number of miles driven if the cost is $46. Write a linear function to model the cost C(d) of a one-day rental driven d miles. (Use integers or decimals for any numbers in the expression.) Determine the number of miles driven if the cost is S46. The number of miles driven is(Simplify your answer.)
