| Before |
18 u + 95 |
22 u + 19 |
| Change |
- 18 u |
- 22 u |
| After |
$95 |
$19 |
Amount that Gillian had left
=
15 x 95
= $19
The amount that Jane and Gillian had at first is the same.
22 u + 19 = 18 u + 95
22 u - 18 u = 95 - 19
4 u = 76
1 u = 76 ÷ 4 = 19
Amount that Jane had at first
= 18 u + 95
= 18 x 19 + 95
= 342 + 95
= $437
Total amount that both girls had at first
= 2 x 437
= $874
Answer(s): $874
