To earn #$3000# this month, I need to sell #$15000# worth of products.

Explanation:

Since the salary consists of two components, one fixed at #$500# and the other based on sales, in order to earn #$3000#, I would have to earn #$(3000-500)# or #$2500# from sales alone.

That #$2500# represents one sixth of the sales I must achieve. If we represent the total sales I achieve as #x#, we can write the equation as:

#x/6=2500#

Multiplying both sides by #6#, we get:

#x=6xx2500#

#x=15000#
