Answer: A (t) = 24500 (1+0.03)^t
Explanation:
Hi, to answer this question we have to write a growth function: 
A = P (1+r) ^t 
Where: 
A = amount after growth 
P = initial amount 
r = growth rate (in this case is yearly, since she gets a 3% raise each year) 
t = years 
Replacing with the values given: 
The growth rate must be in decimal form (divided by 100) 
A (t) = 24500 (1+3/100)^t 
A (t) = 24500 (1+0.03)^t
