Answer:
300 + 69x
Explanation:
Given initial population of animals = 300 animals
If the population increases by 23% annualy, yearly increment will be expressed as:
Yearly increment = 23% of 300
Yearly increment = 0.23*300
Yearly increment for = 69
Let the total number of years of be x
Increment after x years = 69x
Increase in population of animals after x years with an annual rate of 23% = Initial population + Increment after x years
= 300 + 69x
Hence, the equation represents a population of 300 animals at the increase and an annual rate of 23% is expressed as 300 + 69x
