Answer:
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
