Answer:
$137,557.93
Step-by-step explanation:
It is convenient to let a spreadsheet do the calculations. The number in the fourth column is the number in the first column divided by the number in the second column and multiplied by the number in the third column.
For example, the weighted average cost of Widgets is ...
... 135,320.00 × 866/2740 = 42,769.02
Then the total of all on-hand inventory is the sum of the inventory costs of the three items: $137,557.93.
