To find out how much the principal spent on these items, we need to add up the cost of each item and then multiply it by the number of teachers.
The first item costs $9.99$9.99. The second item costs $9.50$9.50. And the third item costs $16$16.
Therefore, the total cost per teacher is $9.99 + 9.50 + 16 = 35.49$9.99+9.50+16=35.49.
The principal bought these items for 22 teachers, so the total cost is $35.49 \times 22 = 779.78$35.49×22=779.78.
Therefore, the principal spent $\boxed{\textbf{(B)}\ $318.78}$ on these items.
