The equation can be used to determine the amount of money S(t)  that her savings account has after t years is 
Step-by-step explanation:
A student invests $500 in a savings account 
Principal = $500
Rate of interest = 4% = 0.04
We are supposed to find equation can be used to determine the amount of money S(t)  that her savings account has after t years
Formula : 
Where A is the amount after t years =S(t)
t = time 
r = rate of interest in decimals =0.04
P = Principal=500
Substitute the value in the formula :
So, 

Hence The equation can be used to determine the amount of money S(t)  that her savings account has after t years is
