Abi and Wendy had equal amount of money. Each day, Abi spent $4 and Wendy spent $8. When Abi had $110 left, Wendy had
15 as much money left as Abi. How much money did the two girls have at first?
| |
Abi |
Wendy |
| Before |
4 u + 110 |
8 u + 22 |
| Change |
- 4 u |
- 8 u |
| After |
$110 |
$22 |
Amount that Wendy had left
=
15 x 110
= $22
The amount that Abi and Wendy had at first is the same.
8 u + 22 = 4 u + 110
8 u - 4 u = 110 - 22
4 u = 88
1 u = 88 ÷ 4 = 22
Amount that Abi had at first
= 4 u + 110
= 4 x 22 + 110
= 88 + 110
= $198
Total amount that both girls had at first
= 2 x 198
= $396
Answer(s): $396
