Bought apples at 20 cents each
\n" ); document.write( "Ate two of them
\n" ); document.write( "Made a profit of $2.20
\n" ); document.write( "How many did she buy?
\n" ); document.write( ":
\n" ); document.write( "Let x = no. of apples she bought
\n" ); document.write( "then
\n" ); document.write( "(x-2) = no. of apples she sold
\n" ); document.write( ";
\n" ); document.write( "Sale$ - cost = profit
\n" ); document.write( ".30(x-2) - .20x = 2.20
\n" ); document.write( ".30x - .60 - .20 = 2.20
\n" ); document.write( ".30x - .20x = 2.20 + .60
\n" ); document.write( ".10x = 2.80
\n" ); document.write( "x = $\"2.8%2F.1\"$
\n" ); document.write( "x = 28 apple she originally bought
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solution
\n" ); document.write( ".30(26) - .20(28) =
\n" ); document.write( "7.80 - 5.60 = 2.20 \n" ); document.write( "

\n" );
