Answer:
Your answer would be 170 dollars in commission
Step-by-step explanation:
Mutlipy 3×20=60
Multiply 2×40=80
Add them both to get 140 then add the 60 dollars from the microwave sell.
Equals 200
Turn 8.5% into a decimal which would be 0.85
Since 8.5% is out of 100% or 1 setup the equation
200(1+0.85) = 370
