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