Dylan |
Usha |
| Before |
7 u |
9 p |
| Change |
- 6 u |
- 2 p |
| After |
1 u |
7 p |
Amount that Dylan spent on the marker = 6 u
6 u = 13.80
1 u = 13.80 ÷ 6 = 2.30
Amount that Dylan had at first
= 7 u
= 7 x 2.30
= $16.10
Amount that Usha had at first
= 16.10 + 57.70
= $73.80
Fraction of money that Usha had left
= 1 -
29 =
79 Amount that Usha had at first = 9 p
9 p = 73.80
1 p = 73.80 ÷ 9 = 8.20
Amount that Usha had left
= 7 p
= 7 x 8.20
= $57.40
Answer(s): $57.40
