Business and finance. The cost of producing a number of items x is given by C=mx + b, in which b is the fixed cost and m is the varible cost (the cost of producing one more item).\r
\n" ); document.write( "\n" ); document.write( "a) if the fixed cost is $40 and the variable cost is $10, write the cost equation.
\n" ); document.write( "Cost = 10x + 40
\n" ); document.write( "--------------
\n" ); document.write( "b) Graph the cost equation.
\n" ); document.write( "\"graph%28400%2C300%2C-5%2C5%2C-50%2C50%2C10x%2B40%29\"
\n" ); document.write( "------------------------\r
\n" ); document.write( "\n" ); document.write( "c) The revenue generated from the sale of x items is given by R= 50x. Graph the revenue equation on the same set of axes as the cost equation.
\n" ); document.write( "\"graph%28400%2C300%2C-5%2C5%2C-50%2C50%2C50x%2C10x%2B40%29\"
\n" ); document.write( "----------------------------\r
\n" ); document.write( "\n" ); document.write( "d) How many items must be produced for the revenue to equal the cost (the break-even point)?
\n" ); document.write( "Cost = Revenue
\n" ); document.write( "10x+40 = 50x
\n" ); document.write( "40x=40
\n" ); document.write( "x=1 (one item must be produced to break even.
\n" ); document.write( "------------------\r
