Hi, 

SAT scores: mean = 500 and SD = 100

What SAT score I within the population would have a percentile rank of approximately 99

Let X represent that score

NORMSINV(0.99)= 2.326 = z = (X-500)/100

                232.6 = X - 500

                 732.6 = X  

or 733 SAT Score would have a percentile rank of approximately 99
