The population of two different cities are modeled by the equations shown below. The population (in thousands) is represented by Y in the number of years since 1970 is represented by X. What year (s) did the cities have the same population? What was the population of both cities during the year (s) of equal population?

Answer: years of equal population are 1995 and 2022.

in 1995, population was 425,000 people and in 2022, population was 1,910,000 people.

Step-by-step explanation: Baskinville: y = x2 - 22x + 350

Cryersport: y = 55x - 950

Note that x2 is xsquare not x2

Resolving the quadratic equations carefully will give the values of y and x which represent the population and years.
