7 p |
Difference in the amounts between Sabrina and Wendy
= 10 p - 3 p
= 7 p
Since both Sabrina and Wendy spent an equal amount, the difference in the amounts that Sabrina and Wendy had at first and in the end remains unchanged.
7 p = 56
1 p = 56 ÷ 7 = 8
Amount that Wendy had left
= 3 p
= 3 x 8
= $24
Answer(s): $24
