Answer:

20, -20

==> |x| = 20

because this is absolute value

Let d represents the number of days and m represents the number of miles.

you rent a car using option 1, For d days and m miles.

The required expression for total cost: 0.17m+19.99d

Find the cost for renting car for 2 days and driving 70 miles

 0.17(70)+19.99(2)

 11.9+39.98
