Final answer:
The cost of producing the DVD is $20.
Step-by-step explanation:
The sales price of a DVD is $30 and the markup on the cost is 50%. To find the cost of producing the DVD, we can use the formula:
Cost = Sales Price / (1 + Markup%)
Plugging in the given values, we get:
Cost = $30 / (1 + 0.50) = $30 / 1.50 = $20
Therefore, the cost of producing the DVD is $20.
