Use the following for the next 2 questions: A company forecasts that it will ship 120,000 boxes of product in June. The product has a monthly turnover of 3. The company plans to use its facility to ship 80,000 boxes and the balance of the 40,000 boxes will ship from a rented facility. Space may be rented for a charge of $7 per box per month with an in-and-out handling charge of $0.45 per box shipped. 1. What is the rented (fixed) storage cost for June? - $280,000 - $180,000 - $42,500 - $250,000 - $93,333 - $153,333 - $173,333 2. What is the rented variable cost for June? - $33,333 - $43,333 - $6,000 - $38,000 - $18,000 - $28,000 - $23,333
