This is similar to Section 3.8 Problem 44: A retail appliance store sells 4,000 television sets each year. It costs $10 to store one television set for a year. To reorder, there is a fixed processing cost of $25, plus a $9 shipping fee for each television set. (a) The cost function, in dollars, expressed as a function of *, the number of television sets the store reorders each time ( x is also the lot size the store must maintain), is C(x)= where x is defined between 1 and 4000 (b) To minimize its cost, the lot size the store maintains should be television sets, and the store should place orders each year. (Your answers should be integers. )
