Acar rental company charges an initial fee plus a constant fee per kilometer driven.

the table compares the total distance driven on the trip (in kilometers) and the price of the rental (in dollars).

what is the cost of each kilometer driven?

The cost of each kilometer driven is $0.6

Step-by-step explanation:

Let

x > the total distance driven on the trip (in kilometers)

y > the price of the rental (in dollars)

we have

(110,186) and (170,222) > see the table

step 1

Find the slope of the linear function

m=(222-186)/(170-110)

m=36/60

m=0.6 $/km

The slope of the linear equation is equal to the unit rate

so

The cost of each kilometer driven is $0.6

5+2x=a
