The first thing we need to know is that Henry lends Bryant $125.
Since Bryant wins the raffle, he can sell the item at a higher price and decides to sell it for $250.
Henry buys the product for $250, but since Bryant owes him $125, the product costs $125.
Now Henry already has his product and now he decides to sell it for $300
We subtract from the total value of the product the value of the purchase of the product
Now it should be noted that the value of 125 that he lent to Bryant was not returned to him, so it is time to subtract them from the profit as well.
From the sale of the product he earned $50 but he also bought the raffle ticket for $165 and did not win it so we subtract $165 from the profit
We can see that now the profit is negative, that is, Henry does not have any profit, instead he lost $115
