plus 2 percent commission on the sales above 3 million dollars. In a particular month, she earns 35,000. How much was her total sales?

My Effort:

Let x be her total sales.

35,0000=0.02(x-3,000,000)+15,000

35,0000-15,000=0.02(x-3,000,000)

20,000=0.02(x-3,000,000)

Multiplying both sides by 1/0.02 or 50 (Axiom of Multiplication) to maintain the equality, I got:

(1/0.02)(20,000)=(1/0.02)(0.02)(x-3,000,000)

1,000,000=(1)(x-3,000,000)

1,000,000=x-3,000,000

3,000,000+1,000,000=x

x= 4,000,000 dollars

Thus, Jessie's total sales is 4,000,000, dollars. Yes?
