Difference in the amounts between Shannon and Natalie
= 10 p - 7 p
= 3 p
Since both Shannon and Natalie spent an equal amount, the difference in the amounts that Shannon and Natalie had at first and in the end remains unchanged.
3 p = 15
1 p = 15 ÷ 3 = 5
Amount that Shannon had left
= 10 p
= 10 x 5
= $50
Answer(s): $50
