Valen |
Shiyun |
| Before |
8 u |
3 p |
| Change |
- 7 u |
- 1 p |
| After |
1 u |
2 p |
Amount that Valen spent on the pen = 7 u
7 u = 19.60
1 u = 19.60 ÷ 7 = 2.80
Amount that Valen had at first
= 8 u
= 8 x 2.80
= $22.40
Amount that Shiyun had at first
= 22.40 + 51.70
= $74.10
Fraction of money that Shiyun had left
= 1 -
13 =
23 Amount that Shiyun had at first = 3 p
3 p = 74.10
1 p = 74.10 ÷ 3 = 24.70
Amount that Shiyun had left
= 2 p
= 2 x 24.70
= $49.40
Answer(s): $49.40
