The equation for simple interest is I = PRT. I = interest earned, P = principal/money invested, R = rate as a decimal, T = time in years.
I = (450)(0.03)(4)
I = 54
$54 is your answer
Given that the number of years should be represented with x, the number of fish in the pond after x years should best be represented with f(x). The equation that would best show the given scenario in the problem above is,
f(x) = 500(2^x)
From the given, 500 is used as the initial population of the fish.
