Question 169992: this isn't exactly algebra, but i need help:
Grandma Harris is going to host a huge family gathering on Thanksgiving Day. She has 8 grandkids and his year Grandma has decided that they will all help with the serving or clean up. The kitchen is small so she must select 4 kids to wash dishes after the meal. The others will help with the serving during the meal. The selection is not an easy matter, however, for there are attachments among the children that prevent a free choice of 4 dishwashers. Can you help grandma select a dishwashing crew of 4 to satisfy all these whims?
-Mark will work with anybody.
-Rafi won't wash dishes unless Adena helps too.
-Adena won't work without Ashley.
-Adam won't work without Ashley.
-Jenny will work with anybody.
-Daniel won't wash dishes with Adam unless Liz helps too, and won't work with Adena unless Adam also helps.
-Liz won't work with both Rafi and Adena and won't wash dishes with either Mark or Jenny.
-Ashley won't help unless either Rafi or Daniel wash dishes and won't work with Adena unless Liz works too, and won't work with both Mark or Jenny.
