Question

HELP PLEASE????!!!! ASAP!!!!!!

State the practical meaning of the slope and y-intercept for the situation described.

The cost, in dollars, of a one-day car rental is given by c=25+0.15x where x is the number of miles driven.

a.
$0.15 is the cost per day to rent the car and $25 is the cost per mile.
c.
$15 is the cost per day to rent the car and $0.25 is the cost per mile.
b.
$25 is the cost per day to rent the car and $0.15 is the cost per mile.
d.
$25 is the cost per day to rent the car and $15 is the extra cost for unlimited miles.

Answer 1

c=25+0.15x
c = 0.15x + 25

means 25 is cost per day and 0.25 cents is the cost per mile driven

answer is
b.
$25 is the cost per day to rent the car and $0.15 is the cost per mile.

Answer 2

The slope is the amount it will cost you per mile, in addition to the flat fee represented by the y-intercept. (The cost before driving any miles.)

So b. is the correct answer as;

$25 is the cost per day to rent the car and $0.15 is the cost per mile.
