Difference in the amounts between Zara and Joelle
= 7 p - 4 p
= 3 p
Since both Zara and Joelle spent an equal amount, the difference in the amounts that Zara and Joelle had at first and in the end remains unchanged.
3 p = 6
1 p = 6 ÷ 3 = 2
Amount that Joelle had left
= 4 p
= 4 x 2
= $8
Answer(s): $8
