the growth rate is 7% = 0.07 so try \[y = 295(1.07)^{t}\] where t is years and y is the population

So just simplify 295=(1.07)^2?

sort of. it's y = 295(1.07)^2

solve for y

generally speaking for these types of problems (growth rates) \[y = a(1 + r)^{t}\] is the formula you use. a is the initial population, and r is the growth rate

I got 336.7455. Am I correct?

just round it because the question asks for an approximate. unless its the zombie quail apocalypse where .7455 quails are running around!
