- ? |

After |
1 p |
4 p |
Amount that Natalie had less than Pamela
= 7 u - 4 u
= 3 u
3 u = 48
1 u = 48 ÷ 3 = 16
Amount that Natalie had at first
= 4 u
= 4 x 16
= $64
Amount that Pamela had
= 7 u
= 7 x 16
= $112
The amount that Pamela had at first and in the end remains the same.
7 u = 4 p
4 p = 112
1 p = 112 ÷ 4 = 28
Amount that Natalie had in the end
= 1 p
= $28
Amount that Natalie spent on the birthday present
= 64 - 28
= $36
Answer(s): $36
