Question 896650: PLEASE EXPLAIN AND HELP ME !!!!
The revenue (in millions of dollars) from the sale of x units at a home supply outlet is given by R(x)=0.26x. The profit (in millions of dollars) from the sale of x units is given by P(x)=0.085x-1.1.
What is the cost equation?
What is the break even point?

You can put this solution on YOUR website!
Use the relation:
( Profit ) = ( Revenue ) - ( Cost )
+P%28x%29+=+R%28x%29+-+C%28x%29+
+.085x+-+1.1+=+.2x+-+C%28x%29+
Add +C%28x%29+ to both sides
+C%28x%29+%2B+.085x+-+1.1+=+.2x+
Subtract +.085x+ from both sides
+C%28x%29+-+1.1+=+.115x+
Add +1.1+ to both sides
+C%28x%29+=+.115x+%2B+1.1+
-------------------------
Check:
Say +x+=+1000+
+P%281000%29+=+R%281000%29+-+C%281000%29+
+.085x+-+1.1+=+.2x+-+C%28x%29+
+85+-+1.1+=+200+-+C%28x%29+
+83.9+=+200+-+C%28x%29+
+C%281000%29+=+116.1+
and
+C%28x%29+=+.115x+%2B+1.1+
+C%281000%29+=+115+%2B+1.1+
+C%281000%29+=+116.1+
OK
