Answer: $14371.6
Explanation:
Given that,
According to FIFO method,
Marvin sold = 1,900 units of inventory during the month
Cost of Beginning inventory = 990 × $7.25
                        = $7177.5
on Mar. 10
Cost of Purchase = 570 × $7.73
               = $4,406.1
Remaining purchases = Total units sold - Beginning inventory - number of units purchase on mar 10
                  = 1,900 - 990 - 570
                  = 340 units
Cost of remaining purchases = 340 units × $8.2
                         = $2,788
Total cost of goods sold = Cost of Beginning inventory + Cost of Purchase + Â Cost of remaining purchases
                     = $7177.5 + $4,406.1 + $2,788
                     = $14371.6
