Prime cost includes direct materials and direct labor. We are given the direct material cost of $15,000, and the change in the direct material account balance of $6,000. This means that $6,000 worth of direct materials were used in production. Therefore, the total direct material cost added to production is $15,000 - $6,000 = $9,000.

To calculate the direct labor cost added to production, we need to know the amount of direct labor used. We are given that overhead is applied at 50% of direct labor cost, which means that direct labor cost is equal to 2 times the overhead cost. We are not given any information about overhead, so we cannot calculate the direct labor cost directly.

However, we can use the cost of goods sold and the prime cost percentage to back-calculate the prime cost. Prime cost is equal to the cost of goods sold divided by the prime cost percentage. The prime cost percentage is equal to the sum of the direct material cost and the direct labor cost, divided by the cost of goods sold. Rearranging the formula, we get:

Direct material cost + Direct labor cost = Prime cost percentage x Cost of goods sold

Substituting the given values:

Direct material cost + Direct labor cost = 0.4 x $150,000 = $60,000

Direct material cost + 2 x Direct labor cost = $60,000

Direct labor cost = $60,000 - Direct material cost

Direct labor cost = $60,000 - $9,000 = $51,000

Therefore, the total prime cost added to production is $9,000 + $51,000 = $60,000.

The only answer choice that matches this result is C) $33,000.
