you and ur three friends each get an admission ticket to the town carnival you have a coupon for 20$ off that will save your group money. if the total bill to get into the carnival was 100 how much does each admission ticket cost?
If the total bill to get into the carnival was $100 and the coupon saves your group $20, then the group would only need to pay $100 - $20 = $<<100-20=80>>80.
Since there are four people in the group, each admission ticket would cost $80 / 4 = $<<80/4=20>>20 each. Answer: \boxed{20}.
