So lets look at this problem. Ron has 20 pennies. Pam has 20 pennies. If Ron has 4 groups each group will have 5 pennies to add up to 20. Pam will have 5 groups and each group will have 4 pennies to add up to 20.
Therefore Ron will have more pennies in his group.
7.50 25% also equals 1/4 so divide 130.00 by 4 which equals 32.50 subtract 32.50 from 130.00 which equals the cost, 97.50 97.50 minus 90$ is 7.50, therefore that is the answer
