overall profits 行业总的利润的增加的不等于个别的也增加

且，利润的增加不一定是Homes built 带来的。。。

Ungrounded assumption that the owners of newly-build house will buy carpet.

Gratuitous assumption that Carpet manu's profit come from the increased sales.

Baseless assumption that TRCC's current service ability cannot satisfy the new demand.  

1)gratuitous assumption-Homes built larger than those built just 10 years ago does not guarantee more carpet consumption-most people build new home choose wooden floor rather than carpet;

2)carpet manufacturers had greater overall profits does not guarantee the greater profits in carpet cleaning services-technologies make carpet production with lower cost and high quality possible,but little room for improving carpet cleaning services and the profitability remains relatively constant; 

3)should take out a loan to buy an additional truck for our fleet-currently half of trucks are usually not in use,there is no need to buy another truck even if the demand for service increase.
