| Before |
14 u + 120 |
16 u + 108 |
| Change |
- 14 u |
- 16 u |
| After |
$120 |
$108 |
Amount that Gillian had left
=
910 x 120
= $108
The amount that Nora and Gillian had at first is the same.
16 u + 108 = 14 u + 120
16 u - 14 u = 120 - 108
2 u = 12
1 u = 12 ÷ 2 = 6
Amount that Nora had at first
= 14 u + 120
= 14 x 6 + 120
= 84 + 120
= $204
Total amount that both girls had at first
= 2 x 204
= $408
Answer(s): $408
