Final answer:
To find the cashier's rate of ringing up customers per minute, divide the number of customers (2) by the time it took (8 minutes), resulting in a rate of 0.25 customers per minute.
Step-by-step explanation:
The question asks us to find the cashier's rate of ringing up customers per minute if the cashier rings up 2 customers in 8 minutes. To find the rate, divide the total number of customers by the total number of minutes. This calculation is done as follows:
- Number of customers: 2
- Total time: 8 minutes
- Rate = Number of customers / Total time
- Rate = 2 customers / 8 minutes
- Rate = 0.25 customers per minute
Therefore, the correct answer is A. 0.25 customers/min.
