=7-42 Outdoors Inn (see Problem 7-41) expanded its tentmaking operations later in the year. While still making the Double Inn tent, it is also making a larger tent, the Family Rolls, which has four rooms. The company can produce up to a combined total of 280 tents per month. The following table provides the demand that must be met and the production costs for the next 3 months. Note that the costs will increase in month 2. The holding cost for keeping a tent in inventory at the end of the month for use in the next month is estimated to be $6 per tent for the Double Inn and $8 per tent for the Family Rolls.
