A rental truck costs $50 plus $0.50 (67)

Question

per mile.
(a) Write an equation that gives the cost C of driving
the truck x miles.
(b) Use the intersection-of-graphs method to determine
the number of miles that the truck is driven
if the rental cost is $80.
(c) Solve part (b) numerically with a table of values.

Answer 1

a. C = 0.50x + $50.

b C = 0.50x + 50 = 80
0.5x = 80-50 = 30
X = 60 miles.

c. Solve the Eq using several values of
x.
