3 u |
5 u |
| Change |
- ? |

| After |
1 p |
2 p |
Amount that Jane had less than Victoria
= 5 u - 3 u
= 2 u
2 u = 40
1 u = 40 ÷ 2 = 20
Amount that Jane had at first
= 3 u
= 3 x 20
= $60
Amount that Victoria had
= 5 u
= 5 x 20
= $100
The amount that Victoria had at first and in the end remains the same.
5 u = 2 p
2 p = 100
1 p = 100 ÷ 2 = 50
Amount that Jane had in the end
= 1 p
= $50
Amount that Jane spent on the birthday present
= 60 - 50
= $10
Answer(s): $10
