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:
[tex]Total\ sales = Basic\ Salary + 0.04(Total\ sales)[/tex]
[tex]S = 500 + 0.04x[/tex]
[tex]1200=500+0.04x[/tex]
[tex]0.04x=1220-500[/tex]
[tex]0.04x=720[/tex]
[tex]x = \frac{720}{0.04}[/tex]
[tex]x = \$18,000[/tex]
Therefore, Lixins monthly sales are $18,000.
