Difference in the amounts between Gillian and Emily
= 7 p - 4 p
= 3 p
Since both Gillian and Emily spent an equal amount, the difference in the amounts that Gillian and Emily had at first and in the end remains unchanged.
3 p = 24
1 p = 24 ÷ 3 = 8
Amount that Gillian had left
= 7 p
= 7 x 8
= $56
Answer(s): $56
