To solve this problem, we need to first convert 5 minutes and 15 seconds to a decimal form of minutes.
5 minutes is equal to 5.0 minutes, and 15 seconds is equal to 15/60 = 0.25 minutes. Therefore, the total time in minutes is:
5.0 + 0.25 = 5.25 minutes
Next, we can multiply the number of copies made per minute by the total time in minutes to find the total number of copies made:
36 copies/minute x 5.25 minutes = 189 copies
Therefore, the copy machine makes 189 copies in 5 minutes and 15 seconds.
