You can put this solution on YOUR website!
initial price = p
\n" ); document.write( "increased by 10% -> the price will be: p + 10% * p = p + 0.1p = 1.1p
\n" ); document.write( "decreased the new price by 25% -> the price will be:
\n" ); document.write( "1.1p - 25% * 1.1p
\n" ); document.write( "= 1.1p - 0.25 * 1.1p
\n" ); document.write( "= 1.1p - 0.275p
\n" ); document.write( "= 0.825p
\n" ); document.write( "= 82.5% * p (C)
\n" ); document.write( "
\n" ); document.write( "
