Simon had 3 times as much money as Elijah. After Elijah's father gave Elijah $36, the amount of money Simon had become $6 less than that of Elijah's. How much did Elijah have in the end?

Elijah |
Simon |
| Before |
1 u |
3 u |
| Change |
+ $36 |
|
| After |
1 u + $36 |
3 u |
The amount that Simon had remains unchanged.
If Simon had another $6, Elijah and Simon would have the same amount in the end.
3 u + 6 = 1 u + 36
3 u - 1 u = 36 - 6
2 u = 36 - 6
2 u = 30
1 u = 30 ÷ 2 = 15
Amount that Elijah had in the end
= 1 u + 36
= 15 + 36
= $51
Answer(s): $51
