c.
According to the model, would it be possible to supply bins to 100% of the population? Explain
c.
Answer to Problem 71E
No it is not possible.
Explanation of Solution
Given information:
The cost
According to the model, would it be possible to supply bins to 100% of the population? Explain.
Calculation:
No, would it be possible to supply bins to 100% of the population using the model because the expression for C becomes undefined as
Hence, the result is NO.

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.
