Final answer:
The relevant cost of the 170 kilograms of raw material when deciding whether to proceed with the special project is $1,305.
Step-by-step explanation:
The relevant cost of the 170 kilograms of raw material when deciding whether to proceed with the special project is calculated by comparing the cost of using the old raw material versus buying new supplies.
If the company uses the old raw material, the cost would be the original cost of $2,036 minus the proceeds from selling the raw material at the discounted price of $7.00 per kilogram, minus the delivery cost of $84. This total cost would be $1,305.
Therefore, the relevant cost of the 170 kilograms of the raw material is $1,305.
