in the function F(t) = 30(0.97)^t, what is the rate of change? A) 3% growth B) 3% decay C) 97% decay D) 97% growth

A=P(1+r)^t where r is the rate as a decimal. Find r and multiply by 100 to get the percentage.

your sign will indicate whether it is growth or decay. Positive = growth, negative = decay.

1+r = .97 solve for r

r=-0.03
