Sabrina |
Jade |
| Before |
3 u |
5 u |
| Change |
- ? |
|
| After |
1 p |
2 p |
Amount that Sabrina had less than Jade
= 5 u - 3 u
= 2 u
2 u = 48
1 u = 48 ÷ 2 = 24
Amount that Sabrina had at first
= 3 u
= 3 x 24
= $72
Amount that Jade had
= 5 u
= 5 x 24
= $120
The amount that Jade had at first and in the end remains the same.
5 u = 2 p
2 p = 120
1 p = 120 ÷ 2 = 60
Amount that Sabrina had in the end
= 1 p
= $60
Amount that Sabrina spent on the birthday present
= 72 - 60
= $12
Answer(s): $12
