Answer and Explanation:
For calculating the average of the monthly productivity, first, we have to determine the total hours, and then units per machine hours
Therefore, the formula to figure out the total hours is
= Hours per machine × Number of machines
For JAN = 325 × 3 = 975 hours
For FEB = 200 × 5 = 1,000 hours
For MAR = 400 × 4 = 1,600 hours
For APR = 320 × 4 = 1,280 hours
Now, the units per machine hours equivalent to
= Units produced ÷ total hours
For JAN = 2,300 units ÷ 975 hours = 2.36
For FEB = 1,800 units ÷ 1,000 hours = 1.8
For MAR = 2,800 units ÷ 1,600 hours = 1.75
For APR = 3,000 units ÷ 1,280 hours = 2.34
Now, the average of the monthly productivity equals to
= (2.36 + 1.8 + 1.75 + 2.34) ÷ 4
= 2.06 units per machine hour
