1.) A graduate program at a university has an admission eligibility policy that requires applicants to be in the top 20% of admissions test scores. If the test scores have a mean score of 1485 with a standard deviation of 240, what is the test score that determines the cut-off for the top 20%?

I know that this problem has to do with Z-score but I’m not sure how to go about calculating it!
