You can put this solution on YOUR website! B= 4C Note that the problem is telling us that B= 4C. We will use this value for B next:
B-12 = C+6 Substitute for B:
4C-12 = C+6 Add 12 on both sides
4C = C+18 Subtract C on both sides:
3C = 18 Divide both sides by 3:
C = 6 So Cathy had 6, and Betty 4 times more:
B = 6*4 = 24
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The problem says that "after Betty had spend $12 and Cathy had received $6,they had the same amount of money" Let's see if we have the right answers:
B: 24-12=12
C: 6+ 6 =12
We have the correct answer
