Question 1166842
.
Hello this is our activity in the school but my teacher is not good at explaining. Please help me with the solution. Thankyou.


The Atlas Fertilizer Company has two plants where the products are made. In a week, plant A can
make at most 40 tons of fertilizers and plant B can make at most 50 tons of fertilizer per week. The
production manager wants to make a total of at least 70 tons of fertilizers per week. The amount of
particulate matter in the atmosphere over the nearby town is measured weekly and found to be 20
pounds for each ton of product made in plant A and 40 pounds for each ton of product made in plant
B. How many tons should be made weekly in each plant to minimize the total amount of particulate
matter in the atmosphere? 
~~~~~~~~~~~~~~~~~~~



            This problem is for common sense and mental solution.



<pre>
From the condition, it is clear that as many as possible production should be made at

the plant A, since it is more ecologically clean, and the rest can be (and should be) made

at the plane B.



<U>ANSWER</U>.  40 tons at plant A and the rest 30 tons at plant B.

Solved.
