Yen and Victoria had equal amount of money. Each day, Yen spent $19 and Victoria spent $23. When Yen had $90 left, Victoria had
13 as much money left as Yen. How much money did the two girls have at first?
| |
Yen |
Victoria |
| Before |
19 u + 90 |
23 u + 30 |
| Change |
- 19 u |
- 23 u |
| After |
$90 |
$30 |
Amount that Victoria had left
=
13 x 90
= $30
The amount that Yen and Victoria had at first is the same.
23 u + 30 = 19 u + 90
23 u - 19 u = 90 - 30
4 u = 60
1 u = 60 ÷ 4 = 15
Amount that Yen had at first
= 19 u + 90
= 19 x 15 + 90
= 285 + 90
= $375
Total amount that both girls had at first
= 2 x 375
= $750
Answer(s): $750
