Ann bob and cindy had some money. Ann had 20% of the total of the three kids.Bob's amount is 50% of the total amount of ann's and cindys. if cindy has $48 more than bob, how much money does cindy have?

Answer 1

a = .2 (a + b + c)

4a = b + c

b = .5 (a + c) ... 2b = a + c
... a = 2b - c ... b + c = 8b - 4c
... 5c = 7b ... 5b + 240 = 7b
... b = 120

c = b + 48 = 168
