| Before |
2 u |
7 u |
| Change |
- ? |

| After |
1 p |
8 p |
Amount that Victoria had less than Julie
= 7 u - 2 u
= 5 u
5 u = 40
1 u = 40 ÷ 5 = 8
Amount that Victoria had at first
= 2 u
= 2 x 8
= $16
Amount that Julie had
= 7 u
= 7 x 8
= $56
The amount that Julie had at first and in the end remains the same.
7 u = 8 p
8 p = 56
1 p = 56 ÷ 8 = 7
Amount that Victoria had in the end
= 1 p
= $7
Amount that Victoria spent on the birthday present
= 16 - 7
= $9
Answer(s): $9
