Answer:
The simple interest can be modeled by a linear function.
Step-by-step explanation:
We know that,
The equation to find the simple interest is, [tex]I=Prt[/tex],
where I = simple interest, P = Principle amount, r = rate of interest and t = amount of time.
Now, while calculating the simple interest, 'time is usually a variable term'.
So, [tex]I=Prt[/tex] implies [tex]I=kt[/tex], where [tex]k=Pr[/tex] is a constant.
Thus, the equation [tex]I=kt[/tex] represents a linear function.
Hence, the simple interest can be modeled by a linear function.
