You can put this solution on YOUR website!
p(x) = r-(65x+5400)
\n" ); document.write( "Revenue in this case is the total pieces sold and is calculated by multiplying x times the selling price.
\n" ); document.write( "Cost is represented by variable cost 65 times number of pieces made x plus fixed expenses of 5400
\n" ); document.write( "Why is variable cost per unit? Because v.c. is made up of labor per unit, raw material per unit, machine time per unit
\n" ); document.write( "What is fixed cost? Costs that don't go away if your production volumes go down. In fact, if you stop producing completely you will still have a lot of the fixed costs like rent and insurance. \n" ); document.write( "

\n" );
