Difference in the amounts between Tammy and Diana
= 5 p - 3 p
= 2 p
Since both Tammy and Diana spent an equal amount, the difference in the amounts that Tammy and Diana had at first and in the end remains unchanged.
2 p = 16
1 p = 16 ÷ 2 = 8
Amount that Tammy had left
= 5 p
= 5 x 8
= $40
Answer(s): $40
