Don's Car Rentals charges a flat rate of $35 per day plus $2 per mile. If the number of miles is represented by m, what is the a
Mumz [18]

Given that, Don's Car Rentals charges a flat rate of $35 per day plus $2 per mile.

The number of miles is represented by m.

For 1 mile the charge is $2. So, for m miles the charges will be 2m.

Since, Don's Car Rentals charges a flat rate of $35 per day .

So, total charge must be the sum of 35 and 2m.

Hence, the algebraic expression representing the overall rate for the day is

35 + 2m.

Hope this helps you.
