Answer:

$x = -4$

Step-by-step explanation:

Take out 3x from both sides:

5x - 3x = 3x - 3x

2x = 0

2x + 9 = 1

Take out 9 from both sides:

9 - 9 = 1 - 9

0 = -8

Divide 2 from both sides:

$\frac{2x}{2} = \frac{-8}{2}$

$x = -4$

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;

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

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