c. 5+o.5 m



d. 5m + 0.5D

Answer 1

we can simply let the number of miles be M, since if one mile the cost will be,
no. of mile * cost per mile, we can utilise this relationship and construct the following equation, Total cost = M(5 + 0.5), i.e. answer is one

Answer 2

Note that a charge of $5.00 is going irrespective of the miles traveled. Treat that $5 charge as a constant. The variable is the "cost per mile" which is .5 (50 cents).

Let C = cost
Let M = number of miles traveled.

C =$.5M + $5.00
