5 p |
Difference in the amounts between Yoko and Olivia
= 8 p - 3 p
= 5 p
Since both Yoko and Olivia spent an equal amount, the difference in the amounts that Yoko and Olivia had at first and in the end remains unchanged.
5 p = 45
1 p = 45 ÷ 5 = 9
Amount that Yoko had left
= 8 p
= 8 x 9
= $72
Answer(s): $72
