Difference in the amounts between Xylia and Sarah
= 7 p - 4 p
= 3 p
Since both Xylia and Sarah spent an equal amount, the difference in the amounts that Xylia and Sarah had at first and in the end remains unchanged.
3 p = 33
1 p = 33 ÷ 3 = 11
Amount that Xylia had left
= 7 p
= 7 x 11
= $77
Answer(s): $77
