7 p |
Difference in the amounts between Emma and Natalie
= 10 p - 3 p
= 7 p
Since both Emma and Natalie spent an equal amount, the difference in the amounts that Emma and Natalie had at first and in the end remains unchanged.
7 p = 49
1 p = 49 ÷ 7 = 7
Amount that Natalie had left
= 3 p
= 3 x 7
= $21
Answer(s): $21
