2 p |
Difference in the amounts between Kylie and Zara
= 5 p - 3 p
= 2 p
Since both Kylie and Zara spent an equal amount, the difference in the amounts that Kylie and Zara had at first and in the end remains unchanged.
2 p = 4
1 p = 4 ÷ 2 = 2
Amount that Zara had left
= 3 p
= 3 x 2
= $6
Answer(s): $6
