Elijah had $40 more than Min. After Min spent
17 of her money, Elijah had twice as much money as Min. How much money did Elijah have at first?
| |
Elijah |
Min |
| Before |
12 u |
7 u |
| Change |
|
- 1 u |
| After |
12 u |
6 u |
Amount that Elijah had in the end
= 2 x 6 u
= 12 u
If Min had another $40 at first, the amounts that Elijah and Min each had at first will be the same.
12 u = 7 u + 40
12 u - 7 u = 40
5 u = 40
1 u = 40 ÷ 5 = 8
Amount Elijah had at first
= 12 u
= 12 x 8
= $96
Answer(s): $96
