Difference in the amounts between Opal and Sabrina
= 7 p - 5 p
= 2 p
Since both Opal and Sabrina spent an equal amount, the difference in the amounts that Opal and Sabrina had at first and in the end remains unchanged.
2 p = 8
1 p = 8 ÷ 2 = 4
Amount that Sabrina had left
= 5 p
= 5 x 4
= $20
Answer(s): $20
