a 6 pack of undershirts cost 13.98. This is 3.96 less than the cost of buyng 6 individual shirts if each undershirt cost the same amount , how much does each undershirt cost when purchased individually.
So you know the pack is 13.98 and is 3.96 less that 6 shirts individually. So you add 13.98 and 3.96 together and then divide that by 6 which will give you the individual shirt amount. The answer will be 2.99 per shirt.
