To find: The amount money a women invest in the municipal bond, bank certificate bond and high-risk bond for the maximum interest.
Answer to Problem 14P
Women invest
Explanation of Solution
Given:
The total amount of money is
The municipal bond pays
The amount of money a women invested in municipal bond is three times the invested in bank certificates.
Women invest no more than
Calculation:
Suppose the amount invested in the municipal bond is x and the amount invested in the bank certificate bond is y for the maximum interest.
Then the amount invested in the high risk bond is
Use the given information to make the inequalities and the objective function for the feasible region.
The required information is shown in the table below.
municipal bond | Bank certificate bond | high-risk bond | |
Amount of money | x | y |
|
The objective function is,
The constraint to get the feasible region has shown below.
Now, take the equalities of the above inequalities,
And,
And,
And,
Substitute
Substitute 2250 for y in equation (3),
Thus, the intersection point is
Substitute
Substitute 3000 for y in equation (3),
Now, draw the graph of the above equations,
Figure (1)
The vertices which lies in the feasible region is shown below.
Substitute the 6750 for x and 2250 for y in the objective function
Substitute the 9000 for x and 3000 for y in the objective function
Substitute the 12000 for x and 0 for y in the objective function
Substitute the 9000 for x and 0 for y in the objective function
So, all the satisfies these vertices are shown in the table below.

| 990 |
| 960 |
The maximum interest rate is 1012.5 at the investment
Thus, a women invest

If the problem can be solved using precalculus, solve it. If the problem seems to require calculus, use a graphical or numerical approach to estimate the solution. STEP 1: Consider the figure in part (a). Since this region is simply a triangle, you may use precalculus methods to solve this part of the problem. First determine the height of the triangle and the length of the triangle's base. height 4 units units base 5 STEP 2: Compute the area of the triangle by employing a formula from precalculus, thus finding the area of the shaded region in part (a). 10 square units STEP 3: Consider the figure in part (b). Since this region is defined by a complicated curve, the problem seems to require calculus. Find an approximation of the shaded region by using a graphical approach.
