Answer:

D. Marcus rent a car for 5 days

Step-by-step explanation:

You can solve this by simply plugging the answer choices into the variable d for both equations and comparing the total costs.

When you plug in 5 days you get:

Plan A

C = 30 x 5

C = 150

Plan B

C = 25 x 5 + 15

C = 140

The cost is less for Plan B in this case, so it is better to use Plan B when renting for 5 days.

To find the m(slope) of our graph we can take two points from the graph, im going to use (0,2) and (1,8) the formula for slope is y2-y1/x2-x1
Plug the points in to get 8-2/1-0
The slope of this equation is 6.

For the y-intercept we just find where the line meets the y-axis and that is at 2.

The equation for this graph is y=6x+2
