Difference in the amounts between Jean and Pamela
= 10 p - 7 p
= 3 p
Since both Jean and Pamela spent an equal amount, the difference in the amounts that Jean and Pamela had at first and in the end remains unchanged.
3 p = 33
1 p = 33 ÷ 3 = 11
Amount that Jean had left
= 10 p
= 10 x 11
= $110
Answer(s): $110
