Cookie bakes 25 pies for the farmers market. She charges $7 for an apple pie and $10 for a cherry pie, she sells out of all her pies so her total sales are $205.
\n" ); document.write( "How many pies were apple and how many were cherry?
\n" ); document.write( "------
\n" ); document.write( "Quantity Equation::: a + c = 25
\n" ); document.write( "Value Equation:::: 7a+10c = 205
\n" ); document.write( "------
\n" ); document.write( "Modify for elimination:
\n" ); document.write( "7a + 7c = 7*25
\n" ); document.write( "7a +10c = 205
\n" ); document.write( "---------------------
\n" ); document.write( "Solve for \"c\":
\n" ); document.write( "3c = 30
\n" ); document.write( "c = 10 (# of cherry pies sold)
\n" ); document.write( "---------------------------
\n" ); document.write( "Solve for \"\":
\n" ); document.write( "a + c = 25
\n" ); document.write( "a + 10 = 25
\n" ); document.write( "a = $15 (# of apple pies sold)
\n" ); document.write( "================================
