Question

a colony contains 1500 bacteria. the population increases at a rate of 115% each hour. if x represents the number of hours elapsed, which function represents the senerio

Answer 1

f(x) = 1725x + 1500.

1500 is the constant for this scenario so we will use that as b in f(x)=x+b. 1725 is 115% of 1500 so that will be the constant that can be modified by the variable x representing hours, therefore, f(x) = 1725x + 1500.

Answer 2

its f(x)=1500(2.15)x

Hope this helps!
