Final answer:
The budgeted change in inventory levels for the Mason Merchandise Company in December is an $8,000 increase, calculated by subtracting the cost of goods sold ($10,000) from the budgeted merchandise purchases ($18,000).
Step-by-step explanation:
The Mason Merchandise Company has budgeted $40,000 in sales for December. The cost of goods sold (COGS) is 25% of sales, which means COGS will be $40,000 * 25% = $10,000. If the company is planning to purchase $18,000 in merchandise, we can calculate the budgeted change in inventory levels by subtracting the COGS from the amount of merchandise purchased.
Budgeted purchase: $18,000
Budgeted COGS: $10,000
Budgeted change in inventory: $18,000 - $10,000 = $8,000
Therefore, the budgeted change in inventory levels for the month of December would be an $8,000 increase, which corresponds to option d).
