Ethan had $49 more than Xylia. After Xylia spent
25 of her money, Ethan had four times as much money as Xylia. How much money did Ethan have at first?
| |
Ethan |
Xylia |
| Before |
12 u |
5 u |
| Change |
|
- 2 u |
| After |
12 u |
3 u |
Amount that Ethan had in the end
= 4 x 3 u
= 12 u
If Xylia had another $49 at first, the amounts that Ethan and Xylia each had at first will be the same.
12 u = 5 u + 49
12 u - 5 u = 49
7 u = 49
1 u = 49 ÷ 7 = 7
Amount Ethan had at first
= 12 u
= 12 x 7
= $84
Answer(s): $84
