Difference in the amounts between Victoria and Joelle
= 10 p - 7 p
= 3 p
Since both Victoria and Joelle spent an equal amount, the difference in the amounts that Victoria and Joelle had at first and in the end remains unchanged.
3 p = 18
1 p = 18 ÷ 3 = 6
Amount that Victoria had left
= 10 p
= 10 x 6
= $60
