Cody had $33 more than Eva. After Eva spent
15 of her money, Cody had twice as much money as Eva. How much money did Cody have at first?
| |
Cody |
Eva |
| Before |
8 u |
5 u |
| Change |
|
- 1 u |
| After |
8 u |
4 u |
Amount that Cody had in the end
= 2 x 4 u
= 8 u
If Eva had another $33 at first, the amounts that Cody and Eva each had at first will be the same.
8 u = 5 u + 33
8 u - 5 u = 33
3 u = 33
1 u = 33 ÷ 3 = 11
Amount Cody had at first
= 8 u
= 8 x 11
= $88
Answer(s): $88
