Answer:
$60,000
Step-by-step explanation:
under the periodic inventory system, cost of goods sold(COGS) is calculated by the formula given below
COGS = BEGINNING INVENTORY(BI) + cost of goods purchased(COGP) - ENDING INVENTORY (EI)
BI=COGS-COGP+EI
Given in the problem
COGS=122000
COGP=83000
EI=21000
122,000 - 83000 + 21000 = $60,000(EI)
