Question 1174885
<font color=black size=3>
Answer: y = 2x+100


---------------------------------------------
Work Shown:


x = number of miles driven
y = total cost


Each day costs $20 to lease it, ignoring the mileage for now.
This means leasing for five days costs 5*20 = 100 dollars.


If we account for the number of miles driven, then we add on 2x dollars. This is because it costs $2 per mile, and x is the number of miles.


So overall, it costs 2x+100 dollars to drive x miles when you lease the car for 5 days.
We can then write y = 2x+100 is the equation to tie together the mileage (x) and the total cost (y).
