Neave had $30 more than Tiffany. After Tiffany spent
13 of her money, Neave had thrice as much money as Tiffany. How much money did Neave have at first?
| |
Neave |
Tiffany |
| Before |
6 u |
3 u |
| Change |
|
- 1 u |
| After |
6 u |
2 u |
Amount that Neave had in the end
= 3 x 2 u
= 6 u
If Tiffany had another $30 at first, the amounts that Neave and Tiffany each had at first will be the same.
6 u = 3 u + 30
6 u - 3 u = 30
3 u = 30
1 u = 30 ÷ 3 = 10
Amount Neave had at first
= 6 u
= 6 x 10
= $60
Answer(s): $60
