Caden had 4 times as much money as Elijah. After Elijah's father gave Elijah $20, the amount of money Caden had become $5 less than that of Elijah's. How much did Elijah have in the end?
| |
Elijah |
Caden |
| Before |
1 u |
4 u |
| Change |
+ $20 |
|
| After |
1 u + $20 |
4 u |
The amount that Caden had remains unchanged.
If Caden had another $5, Elijah and Caden would have the same amount in the end.
4 u + 5 = 1 u + 20
4 u - 1 u = 20 - 5
3 u = 20 - 5
3 u = 15
1 u = 15 ÷ 3 = 5
Amount that Elijah had in the end
= 1 u + 20
= 5 + 20
= $25
Answer(s): $25
