The weekly income of joe if he earns $250 per week plus 15% of his sales over $10,000 is $1,150.

This is a fee charged by an agent or broker for carrying out a transaction.

For instance, a reseller’s commission:

The real-estate broker charged a four percent commission for their knowledge on bidding for commercial properties; for their intellectual perspective on making a formal offer and the strategy to obtain a mutually satisfying deal with the seller in favour of the buyer.

Sales over $10,000 = $16,000 – $10,000

= $6,000

Joe’s weekly income = Joe’s base income weekly + 15% of sales over $10,000

= $250 + (15% × 6,000)

= 250 + (0.15 × 6,000)

= 250 + 900

= $1,150

Therefore, the weekly income of joe if he earns $250 per week plus 15% of his sales over $10,000 is $1,150
