Let's calculate the total cost of the inventory based on the purchases you mentioned.
Beginning inventory: 10 units at $60 = $600
First purchase: 25 units at $65 = $1625
Second purchase: 30 units at $68 = $2040
Third purchase: 15 units at $75 = $1125
To find the total cost of the inventory, we add up the costs of the beginning inventory and the purchases:
$600 + $1625 + $2040 + $1125 = $5390
So, the total cost of the inventory for the year is $5390.
