Suppose that a college admissions office needs to compare scores of students who take the Scholastic Aptitude test(SAT) wit those who take the american college test (ACT). Suppose that among the college's applicants who take the SAT, scores have a mean of 896, and a standard deviation of 174. Further suppose that among the college's applicants who take ACT score have a mean of 20.6 and standard deviation of 5.2
My question is If applicant Bobby scored 1080 on SAT , how many points above the SAT mean did he score?
i just don't understand how to do it

I think i misunderstood the question.. is it just 1080  896

Yes, from the wording I would draw the same conclusion.
A more interesting question would have been:
What score on the ACT would be equivalent to Bobby's score of 1080 on the SAT ?
