Assume the demand occurs 365 days per year. a. Determine the order quantity. (Round your answer to the nearest whole number.) Order quantity tires b. Determine the reorder point. (Use Excel's NORMSINV() function to find the correct critical value for the given a-level. Do not round intermediate calculations. Round "z" value to 2 decimal places and final answer to the nearest whole number.)
