The cost of a single ticket depends on the number of tickets, t , purchased in a group, as represented by the function cap c times t c of t is equal to 18 point 5 0 dollars when 1 is less than or equal to t comma t is less than 12; c of t is equal to 16 point 0 0 dollars when 12 is less than or equal to t comma t is less than 20; c of t is equal to 14 point 5 0 dollars when 20 is less than or equal to t What is the total cost for 20 tickets?
For a group of 20 tickets, use the rule for 20 or more tickets: each ticket costs $14.50. Multiply $14.50 by 20 to get a total cost of $290.00. The correct choice is $290.00.
