The principal at Gotham Elementary bought each teacher the three items shown above. If the school has 22 teachers, how much did the principal spend on these items?
Since there are 22 teachers, the principal bought 3 items for each one of them, for a total of 22*3 = <<22*3=66>>66 items
If the principal bought each item at the price of $30, he spent a total of 66*30 = $<<66*30=1980>>1980. Answer: \boxed{1980}.
