Answer:
3 registers.
Step-by-step explanation:
At 12 pm, the average wait time was 24 minutes. So, we do 24 divided by the 8 that we want our wait time to be. That will give us the amount of registers we need. 24 divided by 8 is 3. Therefore, there will need to be 3 registers for a wait time of 8 minutes.
Hope this helps! :D
