Answer: Approximately 28 copies per minute.
Explanation:
To find the number of copies the machine makes per minute, we need to first convert the time to minutes.
4 minutes and 45 seconds can be written as 4 + 45/60 = 4.75 minutes.
Next, we can divide the total number of copies (133) by the total time in minutes (4.75):133 copies / 4.75 minutes ≈ 28 copies per minute
Therefore, the copy machine makes approximately 28 copies per minute.
