First, we must find overall how much money all of the appliances Rhonda sold add up to.
800 + 1250 + 120 + 625 + 65= 2860
Second, we must subtract 2000 from our sum.
2860-2000 = 860
Lastly, we have to find what 15% of 860 is.
(.15)(860)= 129
In conclusion, before taxes, Rhonda should get $129 in her commission check.
