Answer:
To calculate the revenue (in dollars) the store collects in c hours, you can use the given information: customers spend an average of $30 every b hours. You need to find out how many customers the store serves in c hours and then multiply that by the average spending per customer.
First, determine the number of periods of b hours in c hours. You can do this by dividing c by b:
Number of periods = c / b
Next, calculate the total revenue by multiplying the number of periods by the average spending per customer:
Total Revenue = (Number of periods) x (Average spending per customer)
Total Revenue = (c / b) x $30
So, the store collects (c / b) times $30 in revenue during c hours.
