EnRG Inc. produces trail mix packaged for sale in convenience stores across Canada. At the beginning of April, EnRG has no inventory of trail mix. Demand for the next three months is expected to remain constant at 50,000 bags per month. EnRG plans to produce 50,000 bags in April. However, many of the employees take vacation in June, so EnRG plans to produce 70,000 bags in May and only 30,000 bags in June. Costs for the three months are expected to remain unchanged.
