5 p |
Difference in the amounts between Shannon and Lucy
= 8 p - 3 p
= 5 p
Since both Shannon and Lucy spent an equal amount, the difference in the amounts that Shannon and Lucy had at first and in the end remains unchanged.
5 p = 10
1 p = 10 ÷ 5 = 2
Amount that Shannon had left
= 8 p
= 8 x 2
= $16
Answer(s): $16
