The following is B and C because it can be written in either of those ways and when you calculate it , you don’t get 144 or 36. Hope this helps. Brainliest is appreciated :)
Answer:
C
Step-by-step explanation:
If you let the convenience fee equal x, then...
(2×17.25)+(2×1)+(2×x)= 40.50
There are 2 girls so we multiply all the charges by 2. Add them together and you'll get 40.50. Now if we solve for x, we will get the amount of the convenience fee.
2×17.25 + 2×1 + 2x = 40.50
34.50 + 2 + 2x = 40.50
36.50 + 2x = 40.50
2x = 40.50 - 36.50
2x = 4
x = 2
Each girl paid a 2 dollar convenience fee.
