Difference in the amounts between Cathy and Gabby
= 8 p - 5 p
= 3 p
Since both Cathy and Gabby spent an equal amount, the difference in the amounts that Cathy and Gabby had at first and in the end remains unchanged.
3 p = 6
1 p = 6 ÷ 3 = 2
Amount that Cathy had left
= 8 p
= 8 x 2
= $16
Answer(s): $16
