Justin |
Yoko |
| Before |
7 u |
9 p |
| Change |
- 2 u |
- 7 p |
| After |
5 u |
2 p |
Amount that Justin spent on the pen = 2 u
2 u = 2.60
1 u = 2.60 ÷ 2 = 1.30
Amount that Justin had at first
= 7 u
= 7 x 1.30
= $9.10
Amount that Yoko had at first
= 9.10 + 39.50
= $48.60
Fraction of money that Yoko had left
= 1 -
79 =
29 Amount that Yoko had at first = 9 p
9 p = 48.60
1 p = 48.60 ÷ 9 = 5.40
Amount that Yoko had left
= 2 p
= 2 x 5.40
= $10.80
Answer(s): $10.80
