Final answer:
Dreamland must produce and sell 700 pillows each month to earn a monthly gross profit of $1,000.
Step-by-step explanation:
To calculate the number of pillows Dreamland must produce and sell each month to earn a monthly gross profit of $1,000, we need to consider all costs involved in production. Firstly, let's calculate the total variable cost per pillow. The raw material cost is $3 per pound and each pillow requires two pounds, so the raw material cost per pillow is $6. The direct labor cost is $4 per hour and it takes one hour to manufacture each pillow, so the direct labor cost per pillow is $4. Therefore, the total variable cost per pillow is $6 + $4 = $10.
Next, we need to calculate the total fixed cost. The fixed supervisory costs are $2,000 per month and the factory rent is $4,000 per month, so the total fixed cost is $2,000 + $4,000 = $6,000.
To determine the number of pillows Dreamland must produce and sell, we can use the following formula:
Number of pillows = (Total fixed cost + Desired profit) / Contribution margin per pillow
Using the given information, the desired profit is $1,000 and the contribution margin per pillow is the selling price ($20) minus the variable cost per pillow ($10), which is $10. Plugging in these values, we get:
Number of pillows = ($6,000 + $1,000) / $10 = 700
Therefore, Dreamland must produce and sell 700 pillows each month to earn a monthly gross profit of $1,000.
