PLS HELP ME AS SOON AS POSSIBLE
Veseljchak [2.6K]

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.

  • 50 + 0.35(80)
  • 50 + 28
  • 78

Thus, the answer is $78.

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

natima [27]

Answer:

$695

Step-by-step explanation:

So if each camera costs $6.95 snd he wants 100 you would multiply by 100. And that would be 6.95×100=695 and a good trick I've learnt is that you just move the numbers 1 column to the left for each zero so if it was 10 you'd move all the numbers 1 column to the left. It is abit hard to explain but you're answer is there just thought that'd help in future.
