Tammy and Roshel had equal amount of money. Each day, Tammy spent $19 and Roshel spent $24. When Tammy had $105 left, Roshel had
47 as much money left as Tammy. How much money did the two girls have at first?
| |
Tammy |
Roshel |
| Before |
19 u + 105 |
24 u + 60 |
| Change |
- 19 u |
- 24 u |
| After |
$105 |
$60 |
Amount that Roshel had left
=
47 x 105
= $60
The amount that Tammy and Roshel had at first is the same.
24 u + 60 = 19 u + 105
24 u - 19 u = 105 - 60
5 u = 45
1 u = 45 ÷ 5 = 9
Amount that Tammy had at first
= 19 u + 105
= 19 x 9 + 105
= 171 + 105
= $276
Total amount that both girls had at first
= 2 x 276
= $552
Answer(s): $552
