3 p |
Difference in the amounts between Abi and Sabrina
= 7 p - 4 p
= 3 p
Since both Abi and Sabrina spent an equal amount, the difference in the amounts that Abi and Sabrina had at first and in the end remains unchanged.
3 p = 36
1 p = 36 ÷ 3 = 12
Amount that Sabrina had left
= 4 p
= 4 x 12
= $48
Answer(s): $48
