Question 107513
using the two cost & distance figures, you cand find the "cost per mile" (slope of the line)


(572-376)/(1800-400)=196/1400=.14


if it costs 14 cents per mile then 376-(.14*400) or 320 represents the "fixed costs"


the equation is (cost)=.14(miles)+320


for b) and c) just plug the numbers into the equation


e) is stuff like car payments - that are NOT milage related
