Cole had 4 times as much money as Simon. After Simon's father gave Simon $31, the amount of money Cole had become $4 less than that of Simon's. How much did Simon have in the end?

Simon |
Cole |
| Before |
1 u |
4 u |
| Change |
+ $31 |
|
| After |
1 u + $31 |
4 u |
The amount that Cole had remains unchanged.
If Cole had another $4, Simon and Cole would have the same amount in the end.
4 u + 4 = 1 u + 31
4 u - 1 u = 31 - 4
3 u = 31 - 4
3 u = 27
1 u = 27 ÷ 3 = 9
Amount that Simon had in the end
= 1 u + 31
= 9 + 31
= $40
Answer(s): $40
