42666 cases

Step-by-step explanation:

P = (Marginal Loss) / (Marginal Loss + Marginal Profit)

P = (35) / (35+15) = 0.7

Considering a normal distribution we can find the corresponding z value by P = 0.7 (which represented the shaded area under the curve)

z = 0.5244

z = (X - Mean Sales) / Standard Deviation

-0.5244 = (X - 45000) / 4450

X = 42666.42 ≅ 42666
