Answer: $90
Explanation:
Given : The cost of one stock = $45
And the value of that stock after 15 years is 3 times the paid price.
i.e. The value of that stock after 15 years =
![3*45=\$135](https://img.qammunity.org/2020/formulas/mathematics/middle-school/wcp5vn82j3y5svm2pe56solviar14b3w3q.png)
Then, the return on owning this stock =
![\text{Value after 15 years -Paid price}](https://img.qammunity.org/2020/formulas/mathematics/middle-school/rwc692ew1q87eyzavwjg4x9wmujlohukhu.png)
![=\$135-\$45=\$90](https://img.qammunity.org/2020/formulas/mathematics/middle-school/q0z7oaoqlvlcsl6w3087535zzebewtl8a9.png)
Therefore, the return on owning this stock = $90
