Answer:
2.27%
Step-by-step explanation:
Lets start by making the names letters, J C and A respectively.
The total is 44 dollars. J paid 34%, which would be 14.96. He pays a total of $15. C paid 50%, which is 22 dollars. A pays 17%, which would be 7.48. She pays a total of $8.
15 + 8 + 22 = $45, meaning they paid an extra 1 dollar. One dollar is 1/44th of $44, or 2.27%.
Note: 2.27% is 2.272727272727 repeated, do what you will with that information, every site is different.
