Final answer:
The machine-hours required to support estimated production is 152,325.
Step-by-step explanation:
The machine-hours required to support estimated production can be calculated by dividing the fixed manufacturing overhead cost by the variable manufacturing overhead cost per machine-hour.
Step 1: Divide the fixed manufacturing overhead cost ($655,000) by the variable manufacturing overhead cost per machine-hour ($4.30) to find the total machine-hours required.
Result: 655,000 / 4.30 = 152,325 machine-hours
