This, as an equation, becomes

1000 + .06x = 2200, where x is the total sales.

.06x = 1200

x = $20,000

If he earned 2200 last month, you have to subtract the original 1000 he already makes, which equals=1200.00
Having earned 1,200.00:
(1200)/(0.06)
Divide 1200 by 0.06 to get 20000.
20,000.00
He sold 20,000 worth of jewelry.
To check your answer, reverse your math:
20000*0.06%
Multiply 20000 by 0.06% to get 1200.
1200
Answer= 20,000
