Emma and Abi had equal amount of money. Each day, Emma spent $8 and Abi spent $18. When Emma had $80 left, Abi had
34 as much money left as Emma. How much money did the two girls have at first?

Emma |
Abi |
| Before |
8 u + 80 |
18 u + 60 |
| Change |
- 8 u |
- 18 u |
| After |
$80 |
$60 |
Amount that Abi had left
=
34 x 80
= $60
The amount that Emma and Abi had at first is the same.
18 u + 60 = 8 u + 80
18 u - 8 u = 80 - 60
10 u = 20
1 u = 20 ÷ 10 = 2
Amount that Emma had at first
= 8 u + 80
= 8 x 2 + 80
= 16 + 80
= $96
Total amount that both girls had at first
= 2 x 96
= $192
Answer(s): $192
