(a)
To find: The number of cases of each drug should be produced in order to maximize profit, if the company makes a profit of $320 on each case of drug A and $500 on each case of drug B.
(a)

Answer to Problem 57E
5 cases of drug A and 8 cases of drug B
Explanation of Solution
Given information: Business: A pharmaceutical company manufactures two drugs. Each case of drug A requires 3 hours of processing time and 1 hour of curing time per week. Each case of drug B requires 5 hours of processing time and 5 hours of curing time per week. The schedule allows 55 hours of processing time and 45 hours of curing time weekly. The company must produce no more than 10 cases of drug A and no more than 9 cases of drug B.
Calculation:
Lots of information here, starting from the end sometimes helps identify the variables.
We are maximizing profit:
Where x is amount of drug A cases and y is the amount of drug B cases
We know that
So,
We know that
The problem says a maximum of 55 hours processing and 45 hours of curing are mandated.
Take the processing hours from each and set
Take the curing hours from each and set
Finally we know that,
Graphing these inequalities you get:
Test each vertex: (you don’t have to test
The company should produce 5 cases of drug A and 8 cases of drug B.
(b)
To find: The maximum profit.

Calculation:
Thus,
The maximum profit is 5750 dollars.

The incoming water can be apportioned in different volumes to each turbine, so the goal of this project is to determine how to distribute water among the turbines to give the maximum total energy production for any rate of flow. Using experimental evidence and Bernoulli's equation, the following quadratic models were determined for the power output of each turbine, along with the allowable flows of operation: 6 KW₁ = (-18.89 +0.1277Q1-4.08.10 Q) (170 - 1.6 · 10¯*Q) KW2 = (-24.51 +0.1358Q2-4.69-10 Q¹²) (170 — 1.6 · 10¯*Q) KW3 = (-27.02 +0.1380Q3 -3.84-10-5Q) (170 - 1.6-10-ºQ) where 250 Q1 <1110, 250 Q2 <1110, 250 <3 < 1225 Qi = flow through turbine i in cubic feet per second KW = power generated by turbine i in kilowattsarrow_forward
