Company A charges an amount based on the cost function, C = Vn + F, where C is the total cost, V is the variable cost, F is the fixed cost, and n is the number of people who attend the wedding. Suppose n is a random variable with ?μ = 46 and ?σ = 9. Also, V = 38 and F = 2850. (Round your answers to the nearest dollar.) (a) What is the mean for the total cost? Answer: dollars (b) What is the standard deviation for the total cost? Answer: dollars
