How does the number of question marks relate to your perceived difficulty with this problem? Is it a direct proportion, direct as the square of the number of question marks, or exponential? If it is exponential, what is the base? Yes, I am mocking you.
How would you express the idea of 5 less than some quantity? How would you express the idea of 3 times some quantity that you are representing with the variable "j"?
