Calculate how many minutes it would take to prepare 900 bags.  You want to find the per unit rate in terms of bag/minutes.

      900 bags divided by 2 minutes  = x bags/minute

Now if Ashley and five friends work on the 900 bags at the unit rate in bags per minute

      Unit rate is divided by (Ashley plus five friends)

        = y bags/minute/per person
