3 p |
8 p |
5 p |
Difference in the amounts between Rachel and Pamela
= 8 p - 3 p
= 5 p
Since both Rachel and Pamela spent an equal amount, the difference in the amounts that Rachel and Pamela had at first and in the end remains unchanged.
5 p = 45
1 p = 45 ÷ 5 = 9
Amount that Pamela had left
= 3 p
= 3 x 9
= $27
Answer(s): $27
