$482.5 is the FINAL ANSWER
To find commission:
We can use the base of 100% being 1650
We can use 5% because thats her commission
Use: 100(x)=1650(5) -> 100(x)=8250 after doing math, youll get the outcome of 82.5 commission
To find the total:
Just add that commission to her total being 82.5 + 400 = 482.5 $
