Answer:
x=5000 I think
Explanation:
1800-1600=200$ difference between choices
this difference equals a 4% commission on the amount of furniture she sells during the month
If the amount of sales is x$, then a 4% commission on the amount is 0.04x$

x=200%2F0.04
x=5000$ amount of sales for that two choices will be equal
