Question

a rental car cost $25 plus $0.25 per mile (a) write an equation that gives the cost C of driving the x miles (b) use the intersection of graph methods to determine the number of miles that the car is driven if the cost is $100 (c) solve part (b) numerically with a table values.

Answer 1

(a)
Let C = cost
Let x = number of miles
C = 0.25x + 25
(b) C = 100
Graph C = 0.25x + 25 and C = 100 on the same x-y plane, and read off the x coordinate of the point of intersection
(c)
Create table
C = 0.25x + 25
Plug in your guesses for x into above equation and solve for C. The values for x = 1,
x = 10 and x = 100 are already in the table below.
x | C
------------
1 | 25.25
10 | 27.50
100 | 50.00
Continue the table with more values until you get C = 100

thank you
