| Before |
3 u |
5 u |
| Change |
- ? |
|
| After |
1 p |
2 p |
Amount that Dana had less than Jen
= 5 u - 3 u
= 2 u
2 u = 44
1 u = 44 ÷ 2 = 22
Amount that Dana had at first
= 3 u
= 3 x 22
= $66
Amount that Jen had
= 5 u
= 5 x 22
= $110
The amount that Jen had at first and in the end remains the same.
5 u = 2 p
2 p = 110
1 p = 110 ÷ 2 = 55
Amount that Dana had in the end
= 1 p
= $55
Amount that Dana spent on the birthday present
= 66 - 55
= $11
Answer(s): $11
