Ive been waiting for 4 hours and still no answer micheal earns a base salary of $100 every week with an additional %13 commission on everything he sells if micheal sold $6050.00 worth of items last week what was his total pay

I helped you with a previous problem that was almost exactly the same as this one.  Did you take notes on the previous problem so that you would have some reference to help you do later problems?

Briefly, Total Pay = $100 + 0.13(total of sales)
                            = $100 + 0.13($6050) = ?

This is a linear relationship.  Initial value was $100 and commissions are 13% of the total of sales.

)because it's going in order of the math sign
