47 as much money left as Vanessa. How much money did the two girls have at first?

Abi |
| Before |
14 u + 84 |
16 u + 48 |
| Change |
- 14 u |
- 16 u |
| After |
$84 |
$48 |
Amount that Abi had left
=
47 x 84
= $48
The amount that Vanessa and Abi had at first is the same.
16 u + 48 = 14 u + 84
16 u - 14 u = 84 - 48
2 u = 36
1 u = 36 ÷ 2 = 18
Amount that Vanessa had at first
= 14 u + 84
= 14 x 18 + 84
= 252 + 84
= $336
Total amount that both girls had at first
= 2 x 336
= $672
Answer(s): $672
