Sherri paid 35% of the bill.
Kim paid 43% of the bill.
Judy paid 22% of the bill.
A - Correct answer.
B - It can't be B because Sherri only paid 35% of the bill.
C - It can't be C because Judy only paid 22% of the bill.
D - It can't be D because Kim and Sherri both paid different amounts.
To work out how much Kim paid, you need to divide 1 by 7 and then multiply that by 3 to get 3/7.
To work out how much Judy paid, you need to add Kim's money together with Sherri's money and take that answer away from 100.
