Mr Z's Unit 5 Review

The cost of renting a motorized scooter is $10.00 for the first 2 miles and 2.75 for each additional mile after. The following expression represents the cost of renting the Scooter where m = miles traveled: 10.00 + 2.75(m - 2). Rewrite this equation as a sum of two terms (Simplify*).

• 2.75m + 4.50

• 10.00 + 2.75m - 2

• 2.75m + 33

• 10.00 + 2.75m - 7.50

Circle the expression that is equivalent to 126+168.
