two plots of land for a total of $120,000. When she sold the first plot, she made a profit of 15%. When she sold the second, she lost 10%. Her total profit was $5500. How much did she pay for each piece of land?
\n" ); document.write( ":
\n" ); document.write( "Let x amt paid for the 1st plot
\n" ); document.write( "then
\n" ); document.write( "(120000-x) = amt paid for the 2nd plot
\n" ); document.write( ":
\n" ); document.write( "Profit - loss = 5500
\n" ); document.write( ".15x - .10(120000-x) = 5500

\n" ); document.write( ".15x - 12000 + .10x = 5500

\n" ); document.write( ":
\n" ); document.write( "Find the cost of the 2nd plot
\n" ); document.write( "120000 - 70000 = $50,000 for the 2nd plot
