Peter makes $7,000 a month plus some extra commission he makes 6% of everything he sells if peter sold $55,000 of jewelry this month what his salary this month

Comment
I'm taking this to mean that he does not have to sell above 7000 to start getting a commission. Furthermore, he makes 6% on the full 55000.

Formula
T = Base Salary +  6% Total Sales
T = Take home salary
Base Salary = 7000
Total Sales = 55000

Substitute and Solve
T = 7000 + 6% * 55000          Change the % to a decimal
T = 7000 + 6/100 * 55000
T = 7000 +  0.06 * 55000
T = 7000 + 3300
T = 10300 dollars.

Conclusion
His take home salary = 10300 dollars <<<< answer.
