Isabel was helping her mom pick apples from their tree in the front yard.  Together they picked 34 apples.  They want to make apple pies.  Each apple pie needs 4 apples, but the apples have to be ripe.  6 of the apples they picked are not ripe.  How many pies can they make?
Isabel has 34 apples - 6 that are not ripe = <<34-6=28>>28 ripe apples.
To make pies they will need 28 apples / 4 apples per pie = <<28/4=7>>7 pies.
