Final answer:
The range of acceptable values for h depends on the details of the problem. If the second constraint is changed to 3x+2y≤ 28, a new feasible region must be graphed, and the solution is commonly found at one of its vertices.
Step-by-step explanation:
The question appears to be regarding a linear programming problem, which typically involves finding the maximum or minimum value of a function subject to certain constraints. The range of acceptable values for h in the second constraint would depend on the specific details of the problem, which are not provided in the question. When the second constraint is changed to 3x+2y≤ 28, the new solution would involve graphing this new constraint on the coordinate plane along with any other existing constraints and the objective function, then finding the vertices of the feasible region that is bounded by these constraints. The optimal solution is often found at one of the vertices of this feasible region.
