Problem
8. Quel sommet maximise $Z=8 x+15 y$ ?
Solution
Step 1 ：Given the function Z = 8x + 15y, we need to find the maximum value.
Step 2 ：Assuming there is a constraint like x + y <= 10.
Step 3 ：Using linear programming techniques, we can solve this problem.
Step 4 ：The maximum value of Z = 8x + 15y is \(\boxed{150}\), which occurs at the point (x, y) = (0, 10).
