а . Suppose that a garment factory purchases and stores light bulbs for the maintenance operations in the sewing hall. The average purchasing cost of a bulb is L.E. 50, the losses due to bad handling account for nearly 10%. The salvage value of the bulb (if not used until the end of its life) is L.E. 15. A box containing 12 bulbs occupies 1,200 cm? of the floor/shelf space of the store, where the annual floor space cost is 360 L.E./m². A bulb is kept in the store for half a year on average, before being used. The interest rate is 5% per quarter, and the inflation rate is 1% per month, and an allowance of 10% is considered for the deterioration of the bulb illumination. Find the cost of a stored bulb after 3 months of its purchasing time.
