calculate

<span>Answer: Skewed to right with mean 0 and S.D. 1
Explanation: Let's assume the z-scores as a linear transformation.
then z=(x-mean)/S.D. = (x-30)/15
z(mean) = (30-30)/15= 0
z(sigma) = 15/15 = 1
Note: Shape does not change.</span>
I wasn't sure if you wanted the percentage, or the amount, so I'll give both.
Amount discount is 8.25.
Percentage discount is 84.999%.
