Difference in the amounts between Natalie and Gillian
= 5 p - 3 p
= 2 p
Since both Natalie and Gillian spent an equal amount, the difference in the amounts that Natalie and Gillian had at first and in the end remains unchanged.
2 p = 24
1 p = 24 ÷ 2 = 12
Amount that Gillian had left
= 3 p
= 3 x 12
= $36
Answer(s): $36
