Tom had 3 times as much money as Elijah. After Elijah's father gave Elijah $34, the amount of money Tom had become $4 less than that of Elijah's. How much did Elijah have in the end?
| |
Elijah |
Tom |
| Before |
1 u |
3 u |
| Change |
+ $34 |
|
| After |
1 u + $34 |
3 u |
The amount that Tom had remains unchanged.
If Tom had another $4, Elijah and Tom would have the same amount in the end.
3 u + 4 = 1 u + 34
3 u - 1 u = 34 - 4
2 u = 34 - 4
2 u = 30
1 u = 30 ÷ 2 = 15
Amount that Elijah had in the end
= 1 u + 34
= 15 + 34
= $49
Answer(s): $49
