Jack had
13 as much money as Lucy at first. After Jack received $197 and Lucy received $61, both of them had the same amount of money. How much did Lucy have at first?

Jack |
Lucy |
Before |
1 u |
3 u |
Change |
+ 197 |
+ 61 |
After |
1 u + 197 |
3 u + 61 |
The amount that Jack and Lucy had in the end is the same.
1 u + 197 = 3 u + 61
3 u - 1 u = 197 - 61 = 136
2 u = 136
1 u = 136 ÷ 2 = 68
Amount that Lucy had at first
= 3 u
= 3 x 68
= $204
Answer(s): $204
