Difference in the amounts between Jean and Shannon
= 7 p - 4 p
= 3 p
Since both Jean and Shannon spent an equal amount, the difference in the amounts that Jean and Shannon had at first and in the end remains unchanged.
3 p = 30
1 p = 30 ÷ 3 = 10
Amount that Shannon had left
= 4 p
= 4 x 10
= $40
Answer(s): $40
