    Given Demand D = 12,500 lights per year

    Set up cost S = $51

    Cost of each light (C) = $1.05

    Holding cost = $0.1 per light per year

    Production p = 100 lights per day

    Usage (d) = 12,500/300 days = 41.66 (round up to 42)

    = 42 lights per day

    a) What is the optimal sizeof the production run?

    Q = √{ (2*D*S) / (H (1 - (d / p))) }

    Q = √{ (2*12500*51) / (0.1 (1 - (42/100))) }

    = 4688.577 = 4689 units

    Q = 4689 units

    b) What is the average holding cost per year?

    Average holding cost per year = average inventory level * H

    = (Q/2) H[1 - (d/p) ]

    = (4689/2) 0.1[1 - (42/100) ]

    = $135.98

    c) What is the average setup cost per year?

    average setup cost per year = (D/Q) S

    = (12,500/4689) * 51

    = 135.97

    d) What is the total cost per year, including the cost of the lights?

    Total cost = D*C + total set up cost + total holding cost

    12,500 * 1.05 + 135.98 + 135.97

    Total cost = $ 13,396.95
