It is given that one third of restaurant is given away and the value that remains is $15000.
If one third is gone that means two thirds of the restaurant is valued at $15000.
Let the value of the restaurant be x.
![\begin{gathered} (2)/(3)x=15000 \\ x=15000*(3)/(2) \\ x=22500 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/k4i8utpr4zfs83l6wd49b2eq5ymyqojtk0.png)
So the original value of the restaurant was $22,500.
Option A is correct.
