3 p |
Difference in the amounts between Xuan and Jean
= 8 p - 5 p
= 3 p
Since both Xuan and Jean spent an equal amount, the difference in the amounts that Xuan and Jean had at first and in the end remains unchanged.
3 p = 12
1 p = 12 ÷ 3 = 4
Amount that Xuan had left
= 8 p
= 8 x 4
= $32
Answer(s): $32
