3 p |
8 p |
5 p |
Difference in the amounts between Gwen and Shiyun
= 8 p - 3 p
= 5 p
Since both Gwen and Shiyun spent an equal amount, the difference in the amounts that Gwen and Shiyun had at first and in the end remains unchanged.
5 p = 10
1 p = 10 ÷ 5 = 2
Amount that Shiyun had left
= 3 p
= 3 x 2
= $6
Answer(s): $6
