Topic Key Ideas, Formulas, and Techniques Examples


Calculating Cost of Goods
Sold, p. 597


  • Cost of goods sold  beginning inventory
    value  purchases 
    ending inventory value


Suppose that Plum Street
Pharmacy began the third
quarter with inventory
valued at $545,636. It
made purchases totaling
$1,275,936, and its end-
of-quarter inventory was
$659,800. Calculate the cost
of goods sold in the third
quarter. (Example 15.2.5)

The Retail Method of
Inventory Valuation, p. 598


  • Multiply the total retail price of inventory by the
    assumed cost percent.


Plum Street Pharmacy
had retail sales totaling
$1,475,023 in the third
quarter. Its cost of goods
sold normally averages
approximately 78%. Use
these facts to estimate the
cost of the goods sold in the
third quarter. (Example 15.2.7)

Cost Basis and Capital Gains,

Sarah recently sold 250
shares of Tesla Nitrates Corp.

for $1,755, 200 shares in 2003
for which she paid $5,578,
and 450 shares that she
