Janine is having seven friends over for breaksfast. Of the eight people who will be eating breakfast, six like orange juice best, and two prefer grapefruit juice. Both kinds of juice cost $2.89 for half gallon, $2.09 for a quart(1/4 of a gallon), and $1.29 for a pint ( 1/8 of a gallon). How many of each size container of each type of juice should Janine buy? Use estimation to decide. Expalin the reasoning.
