37 as much money left as Jane. How much money did the two girls have at first?

Abi |
| Before |
4 u + 84 |
12 u + 36 |
| Change |
- 4 u |
- 12 u |
| After |
$84 |
$36 |
Amount that Abi had left
=
37 x 84
= $36
The amount that Jane and Abi had at first is the same.
12 u + 36 = 4 u + 84
12 u - 4 u = 84 - 36
8 u = 48
1 u = 48 ÷ 8 = 6
Amount that Jane had at first
= 4 u + 84
= 4 x 6 + 84
= 24 + 84
= $108
Total amount that both girls had at first
= 2 x 108
= $216
Answer(s): $216
