It looks like you've provided an image of a problem involving calculus, likely related to finding a maximum or minimum value, or perhaps the optimization of a particular variable. However, due to the small size and low resolution of the image, it's difficult for me to clearly see the problem's details.

To assist you accurately, I would recommend either providing a clearer image or typing out the problem statement. Alternatively, if you have access to any key numbers, variables, or equations in the image, you can share those with me, and I'll help you solve it.

Would you like to try re-uploading the image, or can you describe the problem to me in text?
