Scilla [17]

Based on the commission that Xavier receives from Art Van Furniture, the total value of the furniture sold is $5,500.

= $810

This value of $810 is 18% of the balance of Xavier's sales:

= 810 / 18%
= $4,500

Added to the first $1,000, Xavier's total sales are:

= 4,500 + 1,000

= $5,500
