During one month, the rate for renting a particular car model was $68.56 per day plus 25¢ per mile. For a 1-day rental, let x denote the number of miles driven and let y denote the total cost, in dollars. Complete parts (a) through (e) below. a. Find the equation that expresses y in terms of x. y=0 (Type integers or decimals for any values in the expression. Do not include the $ symbol in your answer. Do not round.) b. Determine bo and b₁. The value of bo is (Type an integer or a decimal. Do not include the $ symbol in your answer. Do not round.) The value of b, is (Type an integer or a decimal.
