7 p |
Difference in the amounts between Jade and Elyse
= 10 p - 3 p
= 7 p
Since both Jade and Elyse spent an equal amount, the difference in the amounts that Jade and Elyse had at first and in the end remains unchanged.
7 p = 77
1 p = 77 ÷ 7 = 11
Amount that Elyse had left
= 3 p
= 3 x 11
= $33
Answer(s): $33
