Answer:
The average processing time per income tax form is more than 3 but less than or equal to 4 days.
Explanation:
The average processing time per income tax form is an average number of days it takes to process an income tax form.
WIP = R x T
Where: WIP = Work in progress; R = Rate; and T = Time
WIP = R X T or 64
WIP = 20T = 64
T = 64 / 20 = 3.2 days
Therefore, the average processing time per income tax form is more than 3 but less than or equal to 4 days.
