Let p = cost of one pillow
\n" ); document.write( ".
\n" ); document.write( "Total cost = 4*p + (4p*.05) = $ 46.20
\n" ); document.write( ".
\n" ); document.write( "4p + .2p = 46.20
\n" ); document.write( ".
\n" ); document.write( "4.2 p =46.20
\n" ); document.write( ".
\n" ); document.write( "p= $11,,,,,answer
\n" ); document.write( ".
\n" ); document.write( "alternate solution,,,1.05 *4p = 46.20
\n" ); document.write( ".
\n" ); document.write( "p= $ 11
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "note increases in cost, like tip or taxes, use 1+ increase
\n" ); document.write( ".
\n" ); document.write( "for decreases in cost, like discounts, use 1- decrease
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "check...46.20/44 = 1.05,,,or 5% increase,,,ok
\n" ); document.write( ".
\n" ); document.write( " \n" ); document.write( "
