  2. Smith’s County Line Heating Supply purchased 10,000 gallons of heating oil for $18,825 from one supplier. The next
    day the company bought an additional 14,000 gallons from another supplier for $24,360. The company already had
    8,250 gallons in inventory at a cost of $12,350 when they made these purchases. They did not make any sales in the
    time between these two purchases.
    a. Calculate the value (at cost) of the company’s heating oil inventory immediately after these purchases, using the
    average cost method.
    b. Suppose that the company sold 16,000 gallons of heating oil from this inventory. Calculate the value (at cost) of
    the remaining inventory using the average cost method.
    c. Suppose that the company then purchased 20,000 additional gallons of heating oil for $38,953. Calculate the
    value (at cost) of the company’s heating oil inventory after this purchase, using the average cost method.
    d. Suppose that the company sells 18,000 gallons from this inventory. Calculate the value (at cost) of the remaining

    c. Calculate the average cost per book (i) at the end of the fi rst week and (ii) at the end of the third week of classes,
    using the average cost method.
