Maria bought seven boxes.
\n" ); document.write( "A week later half of all the boxes were destroyed in a fire.
\n" ); document.write( "There are now only 22 boxes left.
\n" ); document.write( "How many did she start with?
\n" ); document.write( "----------------
\n" ); document.write( "Assume she had x boxes to start with.
\n" ); document.write( "After buying 7 she had x+7 boxes
\n" ); document.write( "She lost (1/2)(x+7) in the fire.
\n" ); document.write( "---
\n" ); document.write( "Equation:
\n" ); document.write( "x - (1/2)(x+7) = 22
\n" ); document.write( "x - (1/2)x - (7/2) = 22
\n" ); document.write( "(1/2)x - (7/2) = 22
\n" ); document.write( "(1/2)x = 51/2
\n" ); document.write( "x = 51 boxes
\n" ); document.write( "---------------------\r
