3 p |
Difference in the amounts between Gem and Zara
= 8 p - 5 p
= 3 p
Since both Gem and Zara spent an equal amount, the difference in the amounts that Gem and Zara had at first and in the end remains unchanged.
3 p = 12
1 p = 12 ÷ 3 = 4
Amount that Zara had left
= 5 p
= 5 x 4
= $20
Answer(s): $20
