Question

Amanda rents each of her cars for a one-time $10.00 insurance charge plus $4.50 per day.create a graph that represents the total dollar amount that you must pay to rent a car for X days

Answer 1

The function that models the cost of renting a car for x days has the following format:

y = a + bx

In which a is the one-time insurance charge and b is the daily cost.

Amanda rents each of her cars for a one-time $10.00 insurance charge plus $4.50 per day.

This means that a = 10, b = 4.5

So

y = 10 + 4.5x

The graphic is a line starting at y = 10, and increasing 4.5 units per day(per unit of x). So
