Answer:
A
Step-by-step explanation:
Because they want you to see the number who is repeating like 80 in the later A is 4 times repeated. I hope it help
y=3x+5
y=mx+b
intercept is 5, postive and represents b
Slope is 3 and represents m
account balance on compound interest = principal amount (1+rate/100)^time
here there are t years so toat months are 12t and ad interest is after each 4 months so time is 12t/4 =3t
now total balance = 3545(1.045)^3t
here 3545 is principal amount , rate is( 1.045-1)×100 =4.5% per 4 months and 3t is time so clearly 3t or 3 is a growth factor hence option A
