(a)
To find:
The linear equation (in slope-intercept form) of the line of constant cost C and the cost function is
The figure shows the region of feasible solutions for the vitamin problem of Example 5 and the straight line graph of all combinations of capsules and chewable tablets for which the cost is $0.40.
(b)
To find:
Do the line of constant cost move up or down as c increases.
The figure shows the region of feasible solutions for the vitamin problem of Example 5 and the straight line graph of all combinations of capsules and chewable tablets for which the cost is $0.40.
(c)
To find:
To find the vertex of the region of feasible solutions that gives the optimal value by inspection.
The figure shows the region of feasible solutions for the vitamin problem of Example 5 and the straight line graph of all combinations of capsules and chewable tablets for which the cost is $0.40.
