As a new field, the demand for data engineers has been increasing in the United States. A study of the Bureau of Labor Statistics (BLS) shows the job outlook for data engineers (scientists) is very promising. There will be 35% increase of the demand for data engineers from 2022 to 2032, which is a lot faster than average. As in all business, one critical factor determining the supply of data engineers is how much they can get paid. Suppose the supply of data engineers (Q) is a function of hourly wage (W). That is Q = c + d* W; where c > 0 and d > 0. The unit of Q is the number of jobs in a year and W is dollar per hour ($/hour)
