Selling mobiles, Jumbo earns a revenue of AED 500 per mobile. This revenue is the amount after deducting the cost of mobile. It incurs a holding cost of AED 25 per mobile per month if a stocked mobile is not sold. Holding cost is a portion of rent, insurance and others. Assume that the unsold units are not carried over to the next period. The supplier takes them. If there is a shortage, the market assigns a good will cost of AED35 a mobile. The store has a stocking policy of 240 mobiles a month. The demand for mobile is normally distributed with a mean of 300 and standard deviation of 50.
