Question

The Cost to rent skis at a local sporting good store is $15 plus $20 per day.Which equation models the relationship between the total cost to rent c and the length of the rental in days d

Answer 1

Answer:

$c=20d+15$

Step-by-step explanation:

Let

d ------> the length of the rental in days

c -----> the total cost to rent in dollars

we know that

The linear equation that represent this situation is

$c=20d+15$

This is the equation of the line in slope intercept form

where

The slope m is

$m=20\ \frac{\ }{day}$

The c-intercept b (value of c when the value of d is zero) is

$b=\ 15$

Answer 2

Answer:

c = 20d + 15

Step-by-step explanation:

answer choices may help if the answer is not one of the choices; but here is the answer that it should be:

20 dollars per day is 20 times the length of rental.

15 is a cost that is added and does not change.

c = the total cost therefore:

c = 20d + 15

hope it helps :)
