It was estimated that the Pittsburgh metropolitan area would have a population of 2,377,800 people at the end of 1993. Its population was expected to increase at the rate of 10 people per day. The metropolitan area of Tampa Bay was estimated to have a population of 2,067,000 at the end of 1993. Its population was expected to increase at the rate of 130 people per day. Assume there are 365 days in a year.
The equation for Pittsburgh is 2,377,800 + 10x
The equation for Tampa is 2,067,000 + 130x
In how many days will the population of the two metropolitan areas were or will be equal?
