document.write( "Suppose the old price per mango was p and you could buy x mangoes for\r\n" );
document.write( "$75 at the old price.  Then\r\n" );
document.write( "\r\n" );
document.write( "xp = 75\r\n" );
document.write( "\r\n" );
document.write( "The price per mango was reduced by 20%, therefore the new price \r\n" );
document.write( "per mango is only 80% of the old price per mango, or 0.8p\r\n" );
document.write( "and now x+5 mangos can be bought for $75, so 0.8p(x+5) = 75\r\n" );
document.write( "\r\n" );
document.write( "So the system of equations is\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Solve that and get the old price p = $3.75,   and the number\r\n" );
document.write( "of mangoes x = 20 that you formerly could buy for $75.\r\n" );
document.write( "\r\n" );
document.write( "The new price per mango is now .80($3.75) = $3\r\n" );
