- ? |

| After |
1 p |
3 p |
Amount that Pamela had less than Kimberly
= 7 u - 3 u
= 4 u
4 u = 48
1 u = 48 ÷ 4 = 12
Amount that Pamela had at first
= 3 u
= 3 x 12
= $36
Amount that Kimberly had
= 7 u
= 7 x 12
= $84
The amount that Kimberly had at first and in the end remains the same.
7 u = 3 p
3 p = 84
1 p = 84 ÷ 3 = 28
Amount that Pamela had in the end
= 1 p
= $28
Amount that Pamela spent on the birthday present
= 36 - 28
= $8
Answer(s): $8
