Kudos for the right answer and explanation
Since we know that 20,000 dollars of commission is based on 125,00 of total revenue, we can create a proportion to determine how much commission is paid on the highest sale of 60,000 dollars.
20,000/125,000 = n/60,000
20/125 = n/60,000
4/25 = n/60,000
240,000 = 25n
9,600 = n
