So we need to start by finding the total price which would be $150 because $130 + $20 would equal $150. Next thing we need to do is find out how many people we have and we have 5 people. We can figure that out by seeing it states “Dolores and four friends” which indicates there is 1 + 4 which would equal 5 then we would divide these 2 numbers we came up with ($150/5) to get $30 each person. Each person paid $30 for the buffet.
