Jenson had $45 more than Emily. After Emily spent
15 of her money, Jenson had twice as much money as Emily. How much money did Jenson have at first?
| |
Jenson |
Emily |
| Before |
8 u |
5 u |
| Change |
|
- 1 u |
| After |
8 u |
4 u |
Amount that Jenson had in the end
= 2 x 4 u
= 8 u
If Emily had another $45 at first, the amounts that Jenson and Emily each had at first will be the same.
8 u = 5 u + 45
8 u - 5 u = 45
3 u = 45
1 u = 45 ÷ 3 = 15
Amount Jenson had at first
= 8 u
= 8 x 15
= $120
Answer(s): $120
