p(x)= -x/2 + 75
\n" ); document.write( "Plug each value of \"x\" back into the equation and solve.
\n" ); document.write( "Values = 2, 7, 9, and 11.
\n" ); document.write( ".
\n" ); document.write( "p(2)= -(2)/2 + 75 [Plug-in (2) instead of (x) and solve]
\n" ); document.write( "p(2)= -(2)/2 + 75
\n" ); document.write( "p(2) = $74
\n" ); document.write( ".
\n" ); document.write( "p(7)= -(7)/2 + 75 [Plug-in (7) instead of (x) and solve]
\n" ); document.write( "p(7)= -(7)/2 + 75
\n" ); document.write( "p(7) = $71.5
\n" ); document.write( ".
