Final answer:
The total revenue from the sales of Kittyz and Katz is $480,000.
Step-by-step explanation:
To calculate the total revenue, we multiply the number of units sold by their respective prices. For Kittyz, we have 20,000 units sold at a price of $15 each, so the total revenue from Kittyz is 20,000 * $15 = $300,000.
For Katz, we have 15,000 units sold at a price of $12 each, so the total revenue from Katz is 15,000 * $12 = $180,000. Adding these two amounts, the total revenue from the sales of Kittyz and Katz is $300,000 + $180,000 = $480,000.
