Harman [31]

Answer:

Lixins monthly sales = $18,000

Step-by-step explanation:

Let x be the total sales.

Given:

Basic salary = $500

Commission on sales = 4% = 0.04

Monthly income = $1220

We need to find her sales for the month.

Solution:

First we write the equation for given situation:

$Total\ sales = Basic\ Salary + 0.04(Total\ sales)$

$S = 500 + 0.04x$

$1200=500+0.04x$

$0.04x=1220-500$

$0.04x=720$

$x = \frac{720}{0.04}$

$x = \$18,000$

Therefore, Lixins monthly sales are $18,000.
