Car Rental Cost. To rent a car, the Acme Rental Company charges $39.95 per day plus $0.20 per mile. There is also a $20 surcharge if the car is rented at the airport. Let y bethe total cost of a rental, x1 the number of days rented, and x2 the number of miles driven.a. If the car is rented from Acme at the airport, obtain the equation that expresses y in terms of x1 and x2.b. What are the values of b0, b1, and b2?c. How much does the total cost change if a car is rented an additional day, but the mileage driven does not change?d. What is the cost of renting an Acme car for 5 days and driving 500 miles?
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
