they produce boxes at a rate of 52 boxes per hour.
\n" ); document.write( "3 hours after they opened, then have 400 boxes in stock.
\n" ); document.write( "3 * 52 = 156 boxes that they made.
\n" ); document.write( "they must have had 400 - 156 = 244 boxes in stock when they opened.
\n" ); document.write( "your equation will be:
\n" ); document.write( "b = 244 + 52 * h
\n" ); document.write( "b is the number of boxes they have in stock.
\n" ); document.write( "h is the number of hours since they opened.
\n" ); document.write( "when h = 3, the equation becomes:
\n" ); document.write( "b = 244 + 52 * 3 = 400
\n" ); document.write( "after 3 hours they have 400 boxes in stock.
\n" ); document.write( "when h = 8, the equation becomes:
\n" ); document.write( "b = 244 + 52 * 8 = 660.
\n" ); document.write( "after 8 hours, they have 660 boxes in stock.\r
\n" ); document.write( "
