Ned to KNow:
z+=blue+%28x+-+mu%29%2Fblue%28sigma%29
0r
blue%28sigma%29%2Az+%2B+mu=blue+%28x%29

z-score of 2.25 with a mean of 500 and a standard deviation of 75
blue%2875%292.25%2B+500+=blue+%28x%29
Always list x as next highest value
(As appropriate to instructions for number of decimal points to be used)
In this case believe next highest Integer Value would be appropriate.
