Erratic usage rates are cushioned by safety stocks. Q) D. Purchase costs per unit differ due to quantity discounts.A manufacturer has a steady annual demand for 23,808 cases of sugar. It costs $6 to store 1 case for 1 year, $31 in set up cost to produce each batch, and $15 to produce each case. Find the number of cases per batch that should be produced to minimize cost The manufacturer should produce _ cases per batch. Round to the nearest whole number as needed.)For the following demand function, find a. E, and b. the values of q (if any) at which total revenue is maximized. p = 800 ~ - 0.2q a. Find the elasticity of demand (E) in terms of q. E(g)= b. Find the values of q (if any) at which total revenue is maximized.
