Kimberly |
Yoko |
Before |
3 u |
5 u |
Change |
- ? |
|
After |
1 p |
4 p |
Amount that Kimberly had less than Yoko
= 5 u - 3 u
= 2 u
2 u = 40
1 u = 40 ÷ 2 = 20
Amount that Kimberly had at first
= 3 u
= 3 x 20
= $60
Amount that Yoko had
= 5 u
= 5 x 20
= $100
The amount that Yoko had at first and in the end remains the same.
5 u = 4 p
4 p = 100
1 p = 100 ÷ 4 = 25
Amount that Kimberly had in the end
= 1 p
= $25
Amount that Kimberly spent on the birthday present
= 60 - 25
= $35
Answer(s): $35
