Answer:
The required formula is: [tex]p=28600+950t[/tex]
Step-by-step explanation:
Consider the provided information.
A city's population was 28,600 people in the year 2015 and is growing by 950 people a year.
Let t is the number of years since 2015, and the population of city is denoted by p,
Each yr population is growing by 950.
That means for t yr since 2015 population will grow 950t
In 2015 the population was 28,600
Thus, the required formula is: [tex]p=28600+950t[/tex]
