Look at photo The cost C, in dollars, of renting a moving truck for a day is given by the function C(x)=0.25x+45, where x is the number of miles driven.
(a) What is the cost if a person drives x=160 miles?
(b) If the cost of renting the moving truck is $120, how many miles did the person drive?
(c) Suppose that a person wants the cost to be no more than $80. What is the maximum number of miles the person can drive?
(d) What is the implied domain of C?
(e) Interpret the slope.
(f) Interpret the y-intercept.
