A farmer sells apples by weight, charging \$2 per pound. He noticed that for every 10 pounds sold, he makes an additional \$5 in profit due to reduced spoilage. If he sold a total of 150 pounds and made \$350 in profit, how much did he make from the sale of the apples alone (excluding the additional profit from reduced spoilage)? Let's think step by step and output the final answer within \boxed{}.
