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