\n" ); document.write( "A trader sells two T-shirts at $48 each. She gains 25% on the cost price for one T-shirt and loses 20% on the cost price for the other T-shirt. Express her net profit or loss as a percentage of the total cost price of the two T-shirts. ......
\n" ); document.write( "(My answer is 2.5% profit, but the answer key has different result)
\n" ); document.write( "

Let cost price of T-shirt she made a 25% profit on, be P
\n" );
document.write( "This means that she sold it for 25% MORE than the cost price, or for 1.25P
\n" );
document.write( "We then get: 
\n" );
document.write( "P, or cost price of T-shirt she made a 25% profit on = 
\n" );
document.write( "Therefore, profit = $48 - $38.40 = $9.60\r
\n" );
document.write( "\n" );
document.write( "Let cost price of T-shirt she made a 20% loss on, be L
\n" );
document.write( "This means that she sold it for 20% LESS than the cost price, or for .8L
\n" );
document.write( "We then get: 
\n" );
document.write( "L, or cost price of T-shirt she made a 20% LOSS on = 
\n" );
document.write( "Therefore, loss = $60 - $48 = $12\r
\n" );
document.write( "\n" );
document.write( "Since the loss ($12) is greater than the profit ($9.60), she incurred a NET LOSS.\r
\n" );
document.write( "\n" );
document.write( "Net loss $2.40 ($12 - 9.60) as a percentage of total cost: $98.40 ($38.40 + 60) =  \n" );
document.write( "

\n" );
