Difference in the amounts between Tammy and Victoria
= 8 p - 3 p
= 5 p
Since both Tammy and Victoria spent an equal amount, the difference in the amounts that Tammy and Victoria had at first and in the end remains unchanged.
5 p = 15
1 p = 15 ÷ 5 = 3
Amount that Tammy had left
= 8 p
= 8 x 3
= $24
Answer(s): $24
