$1-18$ Katherine D'Ann is planning to finance her college education by selling programs at the football games for State University. There is a fixed cost of $$400$ for printing these programs, and the variable cost is $$3.$ There is also a $$1,000$ fee that is paid to the university for the right to sell these programs. If Katherine was able to sell programs for $$5$ each, how many would she have to sell in order to break even?
