A group of friends decides to buy ice cream for a party. They bought 12 chocolate ice cream cones for $2.50 each, 15 vanilla ice cream cones for $2.00 each, and 8 strawberry ice cream cones for $3.00 each. After the party, they realized they had only consumed 80% of the total ice cream cones. If they evenly split the cost among 5 friends, how much did each friend pay? Also, what is the average cost per consumed ice cream cone? Let's think step by step and output the final answer within \boxed{}.
