The constraints of a problem are listed. What are the vertices of the feasible region? x plus y is less than or equal to 5 y is less than or equal to 3 x is greater than or equal to 0 y is greater than or equal to 0

The constraints keep the region in the first quadrant, below y = 3, and below x + y = 5. On the y-axis, the boundary points are (0, 0) and (0, 3). The lines y = 3 and x + y = 5 intersect at (2, 3), and x + y = 5 meets the x-axis at (5, 0). Thus the vertices are (0, 0), (0, 3), (2, 3), and (5, 0), which matches choice B.
