5 p |
Difference in the amounts between Natalie and Min
= 8 p - 3 p
= 5 p
Since both Natalie and Min spent an equal amount, the difference in the amounts that Natalie and Min had at first and in the end remains unchanged.
5 p = 15
1 p = 15 ÷ 5 = 3
Amount that Min had left
= 3 p
= 3 x 3
= $9
Answer(s): $9
