A company rents cars at $40 a day and 15 cents a mile.

Its competitor’s cars are $50 a day and 10 cents a mile.

a) For each company, give a formula for the cost of

renting a car for a day as a function of the distance

traveled

answer :

C1(m) = 40 + 0.15m

C2(m) = 50 + 0.10m

I don't understand why the vertical intercept is 40 in formula c1 and c2

the company rent 15 cents a mile

and the other 10 cents a mile

so as a graph it should start from zero

what is the meaning of $40 and $50 here?

is it the value of you rent the car without miles? or what

the $40 and $50 is vertical intercept for the equation this prices is for rent a car of a day so it's a relationship between cost and days not cost and distance?

Hi,
