There is a 96% customer retention rate for the third quarter.

Given

Jenny owns a salon.

She had 150 customers at the end of the third quarter, 151 customers at the beginning of the third quarter, and five new customers in the third quarter.

<h3>Customer retention rate;</h3>

It determines the percentage of customers that the company has retained over a given period.

The customer retention rate is determined by;

\rm Customer\  retention\  rate=\dfrac{Given \ period - New \ customers}{Initial \ number}\times 100

Substitute all the values in the formula;

\rm Customer\  retention\  rate=\dfrac{Given \ period - New \ customers}{Initial \ number}\times 100\\\\\rm Customer\  retention\  rate=\dfrac{150-5}{151}\times 100\\\\\rm Customer\  retention\  rate=\dfrac{145}{151}\times 100\\\\\rm Customer\  retention\  rate=0.96 times 100\\\\\rm Customer\  retention\  rate=96 \ percent

Hence, there is a 96% customer retention rate for the third quarter.

Ksenya-84 [330]

Answer:  The required volume is 390 mm³.

Step-by-step explanation: Given that the stack on the left is made up of 15 pennies, and the stack on the right is also made up of 15 pennies. The volume of the stack of pennies on the left is 390 mm³.

we are to find the volume of the stack of pennies on the right in cubic millimeters.

The number of pennies on the left and right are same, equal to 15.

Also, the volume of the stack of pennies on the left is 390 mm³.

Since the number of pennies on the right and left are equal, so the volume of the stack on the right and left are also equal.

Therefore, the volume of the stack of pennies on the right is 390 mm³.

Thus, the required volume is 390 mm³.
