Answer:
7a. D)
7b. $78
Step-by-step explanation:
7a: We're given the information that there's a daily fee of $50 and $0.35 per mile driven, which is m. We can write "$0.35 per mile driven" as 0.35m. Then, the total amount of money it costs represented as an expression is 50 + 0.35m, thus, making it answer D).
7b: In this problem, we have to take our previous expression 50 + 0.35m, plug in the value of m, and simplify.
Thus, the answer is $78.
