Percentage problem
Hi, I'm trying to figure out a math problem for my mom. It's mainly percentages and algebra I believe. At her work, each person is supposed to donate \$125 for birthdays through out the year but not everyone donated \$125. There are 14 total people and 10 people donated the full \$125, one person donated \$60, one donated \$70, one donated \$90, and one person donated \$80. So the total donated was \$1550 and \$1113 was left over. So I need to figure out how to evenly distribute the \$1113 that was left over to the 14 people that gave the money. I realize that the 10 people that donated the full \$125 supplied 80% of the total amount donated and the remaining gave 20%. I figured out the percentage given for each person but when I calculated their share it still did not seem fair. I am just having difficulty figuring out how much each person should give back. Can anyone give me any ideas on how to solve this problem? Thanks!

Re: Percentage problem
1550 - 1113 = \$437 spent

to be fair ...

437/14 = 31.21

everyone should get back 31.21 less than they contributed
