$176.10 per month for insurance and car payments and $0.25 per mile for gasoline, oil, and routine maintenance.

(a) find values for m and b so that y=mx+b Modells the monthly cost of driving the car X miles
(B) what does the value of b represents ?

Answer 1

Y=.25x+176.10 Y is the monthly cost and B would be the cost of the insurance every month. X is the amount of miles driven since the .25 stays constant but the amount of miles you drive in a month is different every month, Hence, needs to be a variable that can be adjusted,
