A company markets exercise DVDs that sell for ​$14.95, including shipping and handling.
\n" ); document.write( " The monthly fixed costs​ (advertising, rent,​ etc.) are ​$16,910 and the variable costs​ (materials, shipping,​ etc.) are ​$5.45 per DVD.
\n" ); document.write( "​:
\n" ); document.write( "Let x = no. of DVD's
\n" ); document.write( "(A) Find the cost equation and the revenue equation.
\n" ); document.write( "C(x) = 5.45x + 16910
\n" ); document.write( "R(x) = 14.95x
\n" ); document.write( "​(B) How many DVDs must be sold each month for the company to break​ even?
\n" ); document.write( "14.95x = 5.45x + 16910
\n" ); document.write( "14.95x - 5.45x = 16910
\n" ); document.write( " 9.50x = 16910
\n" ); document.write( "x = 16910/9.5
\n" ); document.write( "x = 1780 DVD's must be sold to break even
\n" ); document.write( "​(C) Graph the cost and revenue equations in the same coordinate system and show the​ break-even point.
\n" ); document.write( "Graph y = 14.95x and y = 5.45x + 16910; looks like this
\n" ); document.write( "
\n" ); document.write( "Blue line shows the revenue at the break even point $26611
\n" ); document.write( ":
\n" ); document.write( "Interpret the regions between the lines to the left and to the right of the​ break-even point.\
\n" ); document.write( "area below the cost line (green), losing money, area above, making a profit
\n" ); document.write( "
\n" );
