Difference in the amounts between Gillian and Yen
= 8 p - 5 p
= 3 p
Since both Gillian and Yen spent an equal amount, the difference in the amounts that Gillian and Yen had at first and in the end remains unchanged.
3 p = 18
1 p = 18 ÷ 3 = 6
Amount that Yen had left
= 5 p
= 5 x 6
= $30
Answer(s): $30
