| Before |
14 u + 88 |
18 u + 16 |
| Change |
- 14 u |
- 18 u |
| After |
$88 |
$16 |
Amount that Betty had left
=
211 x 88
= $16
The amount that Abi and Betty had at first is the same.
18 u + 16 = 14 u + 88
18 u - 14 u = 88 - 16
4 u = 72
1 u = 72 ÷ 4 = 18
Amount that Abi had at first
= 14 u + 88
= 14 x 18 + 88
= 252 + 88
= $340
Total amount that both girls had at first
= 2 x 340
= $680
Answer(s): $680
