Zara and Sabrina had equal amount of money. Each day, Zara spent $5 and Sabrina spent $8. When Zara had $112 left, Sabrina had
14 as much money left as Zara. How much money did the two girls have at first?
| |
Zara |
Sabrina |
| Before |
5 u + 112 |
8 u + 28 |
| Change |
- 5 u |
- 8 u |
| After |
$112 |
$28 |
Amount that Sabrina had left
=
14 x 112
= $28
The amount that Zara and Sabrina had at first is the same.
8 u + 28 = 5 u + 112
8 u - 5 u = 112 - 28
3 u = 84
1 u = 84 ÷ 3 = 28
Amount that Zara had at first
= 5 u + 112
= 5 x 28 + 112
= 140 + 112
= $252
Total amount that both girls had at first
= 2 x 252
= $504
Answer(s): $504
