3 p |
Difference in the amounts between Anna and Emma
= 10 p - 7 p
= 3 p
Since both Anna and Emma spent an equal amount, the difference in the amounts that Anna and Emma had at first and in the end remains unchanged.
3 p = 33
1 p = 33 ÷ 3 = 11
Amount that Anna had left
= 10 p
= 10 x 11
= $110
Answer(s): $110
