Answer:
138 pounds
Explanation:
Let the required weight of the patient be x pounds.
We have that,
156 milligrams of medicine is required for a patient weighing 104 pounds.
Then, 207 milligrams of medicine will be required for a patient having weight as shown below,
Weight of the patient =
![(104 * 207)/(156)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/tui4o2jc91za0k2s492sa5ukpqhvnqtwhw.png)
i.e. x =
![(21528)/(156)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/tjbcurt5m0p096wm7kf171eoht74pstijs.png)
i.e. x =
![138](https://img.qammunity.org/2020/formulas/mathematics/middle-school/8rvfof1pszbwm26zae3lalwbacort3phfx.png)
Hence, the patient needing 207 milligrams of medicine will have the weight 138 pounds.
