Final answer:
Using the retention rate of 70%, Mike's Market will have 1750 customers next week, calculated by multiplying the current 2500 customers by 0.7.
Step-by-step explanation:
To calculate the number of customers who will favor Mike's Market next week, we will use the given percentage of customers that are likely to return. Currently, Mike's Market has 2500 customers. According to the given information, 70% of these customers will shop at Mike's Market the following week.
