A store sells two types of products: Product X and Product Y. The store has a total inventory worth $20,000. If Product X makes up 60% of the inventory value and each unit of Product X costs $40, how many units of Product X are in the inventory?
First, let's find out the total value of Product X in the inventory:

Value of Product X = Total inventory value * Percentage of Product X
                   = $20,000 * 0.6
                   = $12,000

Now, let's calculate the number of units of Product X in the inventory:

Units of Product X = Value of Product X / Cost per unit of Product X
                   = $12,000 / $40
                   = 300

So, there are 300 units of Product X in the inventory.
