- ? |

After |
1 p |
3 p |
Amount that Victoria had less than Nora
= 5 u - 2 u
= 3 u
3 u = 36
1 u = 36 ÷ 3 = 12
Amount that Victoria had at first
= 2 u
= 2 x 12
= $24
Amount that Nora had
= 5 u
= 5 x 12
= $60
The amount that Nora had at first and in the end remains the same.
5 u = 3 p
3 p = 60
1 p = 60 ÷ 3 = 20
Amount that Victoria had in the end
= 1 p
= $20
Amount that Victoria spent on the birthday present
= 24 - 20
= $4
Answer(s): $4
