Steve owns a food truck. He wants to figure his reten September?Round to the nearest whole number. a. Customers at the end of September 130 b . Customers at the beginning of September: c.New customers in September:20 d.Customer retention rate: __

## Step 1<br />The customer retention rate is a measure of how many existing customers a business retains over a given period. It is calculated by dividing the number of customers at the end of the period by the number of customers at the beginning of the period, and then multiplying by 100 to get a percentage.<br /><br />### **Customer Retention Rate = \(\frac{Number\,of\,customers\,at\,the\,end\,of\,the\,period}{Number\,of\,customers\,at\,the\,beginning\,of\,the\,period} \times 100\)**<br /><br />## Step 2<br />In this case, the number of customers at the end of September is 130, and the number of new customers in September is 20. Therefore, the number of customers at the beginning of September is the number of customers at the end of September minus the number of new customers, which is \(130 - 20 = 110\).<br /><br />## Step 3<br />Substitute the values into the formula:<br /><br />### **Customer Retention Rate = \(\frac{130}{110} \times 100 = 118.18\)**<br /><br />## Step 4<br />The problem asks for the answer to be rounded to the nearest whole number. Therefore, the customer retention rate is 118%.
