Question

F(t)=30(0.97)∧t = rate of change

Answer 1

Hey there, Lets solve this together.  

$F(t)=30(0.97)^t$ 

$A = (p+r)^t$  

The variable (R) will be representing the rate as a decimal. 

When you solve for (R) multiply by 100 to get the percentage. A percentage is a rate, number, or amount in each hundred. 

"0.97" will be replaced by "(97/100)"

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the given equation  

$Ft-((30))97/100) * t) = 0$ 

Rewrite the whole as a fraction using  10  as the denominator : 

$ft = ft/1 = ft * 10/10$ 

The equation now takes the shape :
   t  •  (10f-291)  = 0

 f = 291/10 = 29.100

 t = 0


Positive = Growth 

Negative = Decay  

$1 + r = .97$ 

$r = -0.03$
