| After |
2 u |
2 p |
Amount that Reggie spent on the pencil = 7 u
7 u = 13.30
1 u = 13.30 ÷ 7 = 1.90
Amount that Reggie had at first
= 9 u
= 9 x 1.90
= $17.10
Amount that Shiyun had at first
= 17.10 + 25.60
= $42.70
Fraction of money that Shiyun had left

27 Amount that Shiyun had at first = 7 p
7 p = 42.70
