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.

  • [tex]50 + 0.35(80)[/tex]
  • [tex]50 + 28[/tex]
  • [tex]78[/tex]

Thus, the answer is $78.

Have a lovely rest of your day/night, and good luck with your assignments! ♡
