| Before |
10 u + 88 |
18 u + 48 |
| Change |
- 10 u |
- 18 u |
| After |
$88 |
$48 |
Amount that Anna had left
=
611 x 88
= $48
The amount that Gem and Anna had at first is the same.
18 u + 48 = 10 u + 88
18 u - 10 u = 88 - 48
8 u = 40
1 u = 40 ÷ 8 = 5
Amount that Gem had at first
= 10 u + 88
= 10 x 5 + 88
= 50 + 88
= $138
Total amount that both girls had at first
= 2 x 138
= $276
Answer(s): $276
