What is the predetermined overhead rate?

I know that the formula is Estimated Annual Overhead Costs / Expected Annual Operating Activity but I am unsure where to find that information to plug into the formula.

Exercise 15-6 (Part Level Submission) A job cost sheet of Sandoval Company is given below.
