Final answer:
The inventoriable costs per unit associated with Product DCT121 are $283.
Step-by-step explanation:
To calculate the inventoriable costs per unit associated with Product DCT121, we need to add up all the direct and indirect costs that are necessary for the production of one unit of the product. In this case, the direct materials cost is $100, the direct manufacturing labor cost is $70, the variable manufacturing overhead cost is $45, the fixed manufacturing overhead cost is $36, the sales commissions cost is $8, and the administrative salaries cost is $24. Adding up all these costs, we get $100 + $70 + $45 + $36 + $8 + $24 = $283. Therefore, the inventoriable costs per unit associated with Product DCT121 is $283.
