Answer:
The value of Concord Corporation's inventory at May 31, 2022 is: $ 1,440
Explanation:
Weighted Average Cost Method Calculates a New Cost of Inventory following each Purchase
Calculation of New Cost and Inventory value is as follows :
Unit Cost = Total Cost / Total Units
        =((240×$6)+( 480×$6)+(720×$6))/(240+480+720)
        = $ 8,640 / 1440
        = $ 6
Units Remaining = 240+480+720-1200
              = 240
Inventory Value = 240×$ 6
              =$ 1,440
