Help with a percentage math problem?

Question

Julie has a choice between $1800 monthly salary from Pearson's Furniture or a base salary of $1600 and a 4% commission on the amount of furniture she sells during the month. For what amount of sales will the two choices be equal?

Answer 1

Julie must sell $5,000.00 in furniture to get a $200 commission.

$1600+$200 = $1800

If I were Julie I would take the monthly guaranteed money.
