Zane |
Tina |
| Before |
5 u |
8 p |
| Change |
- 3 u |
- 3 p |
| After |
2 u |
5 p |
Amount that Zane spent on the file = 3 u
3 u = 8.10
1 u = 8.10 ÷ 3 = 2.70
Amount that Zane had at first
= 5 u
= 5 x 2.70
= $13.50
Amount that Tina had at first
= 13.50 + 59.30
= $72.80
Fraction of money that Tina had left
= 1 -
38 =
58 Amount that Tina had at first = 8 p
8 p = 72.80

Amount that Tina had left

= 5 x 9.10
= $45.50
Answer(s): $45.50
