1 Answer

  • Answer choices:

    A. less than or equal to 125 pounds

    B. more than 225 pounds

    C. more than 125 pounds but less than or equal to 175 pounds

    D. more than 175 pounds but less than or equal to 225


    A. Less than 125 pounds


    We have the demand = 50 pounds

    The standard deviation is given as 5

    Service level is 95%

    Z critical value is 1.645

    Lead time is 2

    We calculate reorder time as

    RD = DMD * LT + ss

    Reorder point = RD

    Dmd is demand

    Ss is safety stock

    Lt lead time

    Safety stock = 1.645x 5 x √2 = 12

    Reorder = 50x2+12 = 112

    112 is less than 125 so answer choice is A
