Adealer paid $10,000 for a boat at an auction. at the dealership, a salesperson sold the boat for 30% more than the auction price. the salesperson received a commission of 25% of the difference between the auction price and the dealership price. what was the salesperson's commission?
a) $750
b) $1,750
c) $3,250
d) $5,500

Given situation:
=> A deadler paid $10 000 for a boat at an auction.
=> At the dealership, a sales person sold the boat for 30% more than the auction price
=> 10 000 dollars + 30%
=> Then the salesperson received a commission of 25% of the difference between the auction price and the dealership price
=> 10 000 + 25%
Let’s find the solution
=> 10 000 x .30 = 3000
=> 10 000 + 3 000 = 13 000, he sell it for this price
=> then he received a commission
=> 13 000 – 3 000 = 10 000
=> 10 000 x .25
=> 2500 , his commission
