A new computer store offers a special early-bird prize give-away for its grand opening. The
first 12 customers to enter the store between 7 a.m. and 8 a.m. will receive gift certificates
worth various dollar amounts. If 18 customers gather to enter the store between those hours,
how many ways are there to arrange the twelve prize winners?
