COGS= $310
Step-by-step explanation:
Giving the following information:
She bought 20 units of inventory at $11, then 26 units at $9, and finally 18 units at $14.
She sold 30 units in 2019.
Under the FIFO (first-in, first-out) valuation method, the cost of goods sold is calculated using the cost of the firsts units incorporated into inventory.
COGS= 20*11 + 10*9
COGS= $310
