c = 0.07w + 13.3
\n" ); document.write( "c = 0.07w + 13.3 [Plug-in x=375 and solve for \"c\"]
\n" ); document.write( "c = 0.07(375)
\n" ); document.write( "c=39.55
\n" ); document.write( ".
\n" ); document.write( "Check by plugging (c=39.55) back into the original equation and solve for \"w\"
\n" ); document.write( "c = 0.07w + 13.3
\n" ); document.write( "39.55 = 0.07w + 13.3
\n" ); document.write( "39.55 -13.33 = 0.07w + 13.3 - 13.33
\n" ); document.write( "26.22/.07=.07w/.07
\n" ); document.write( "374.57=w [Round off to 375]
\n" ); document.write( ".
\n" ); document.write( "For one wignut, plug-in x=1 and solve for \"c\":
\n" ); document.write( "c = 0.07w + 13.3
\n" ); document.write( "c = 0.07(1) + 13.3
\n" ); document.write( "c = 0.07(1) + 13.3
\n" ); document.write( "c=13.37
\n" ); document.write( ".
\n" ); document.write( "Checking:
\n" ); document.write( "13.37=0.07(1) + 13.3
\n" ); document.write( "13.37=13.37 [Checks out]\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "w + 13.3
\n" ); document.write( ". find the cost when 375 wing nuts are made. what is the average cost to manufacture one wing nut? \n" ); document.write( "
