Luke had $39 more than Natalie. After Natalie spent
15 of her money, Luke had twice as much money as Natalie. How much money did Luke have at first?
| |
Luke |
Natalie |
| Before |
8 u |
5 u |
| Change |
|
- 1 u |
| After |
8 u |
4 u |
Amount that Luke had in the end
= 2 x 4 u
= 8 u
If Natalie had another $39 at first, the amounts that Luke and Natalie each had at first will be the same.
8 u = 5 u + 39
8 u - 5 u = 39
3 u = 39
1 u = 39 ÷ 3 = 13
Amount Luke had at first
= 8 u
= 8 x 13
= $104
Answer(s): $104
