Ryan |
Yen |
| Before |
8 u |
3 p |
| Change |
- 7 u |
- 1 p |
| After |
1 u |
2 p |
Amount that Ryan spent on the marker = 7 u
7 u = 18.90
1 u = 18.90 ÷ 7 = 2.70
Amount that Ryan had at first
= 8 u
= 8 x 2.70
= $21.60
Amount that Yen had at first
= 21.60 + 71.70
= $93.30
Fraction of money that Yen had left
= 1 -
13 =
23 Amount that Yen had at first = 3 p
3 p = 93.30
1 p = 93.30 ÷ 3 = 31.10
Amount that Yen had left
= 2 p
= 2 x 31.10
= $62.20
Answer(s): $62.20
