The two costs are $250 and $ 375. Total profit is $250. One is sold at $450. If first one is sold at that, then profit from it is $200, and profit due to another is only $50, which is not an option.
Hence, second is sold at $450, profit of $75. Hence, profit from first is (250-75)= $175.
Hence, second is sold at $450, profit of $75. Hence, profit from first is (250-75)= $175.
