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.
