Difference in the amounts between Opal and Joelle
= 8 p - 5 p
= 3 p
Since both Opal and Joelle spent an equal amount, the difference in the amounts that Opal and Joelle had at first and in the end remains unchanged.
3 p = 30
1 p = 30 ÷ 3 = 10
Amount that Joelle had left
= 5 p
= 5 x 10
= $50
Answer(s): $50
