Answer:
Waterway Industries's total manufacturing costs incurred in 2020 amounted to $2,140,000
Step-by-step explanation:
The computation of the total manufacturing cost is shown below:
= Raw material + Direct labor cost + Manufactured overhead cost
= $830,000 + $670,000 + $640,000
= $2,140,000
Thus, the total manufacturing cost is comprised of direct raw material, direct labor cost, and the manufacturing overhead cost. That's why we add these three costs.
