A construction company was paid a total of $500,000 for a construction project.  The company's only costs for the project were for labor and materials.  Was the company's profit for the project greater than $150,000 ?

(1)  The company's total cost was three times its cost for materials.

(2)  The company's profit was greater than its cost for labor.

（２）不是说利润比成本多吗，那利润阴囊感超过一半啊，那应该是超过２５００００，可以判断啊
