Difference in the amounts between Xylia and Opal
= 7 p - 4 p
= 3 p
Since both Xylia and Opal spent an equal amount, the difference in the amounts that Xylia and Opal had at first and in the end remains unchanged.
3 p = 36
1 p = 36 ÷ 3 = 12
Amount that Xylia had left
= 7 p
= 7 x 12
= $84
Answer(s): $84
