The growth rate is the a value, or the number before the x value. The answer would be 15.
Answer:
Y:4 X:540
Step-by-step explanation:
ja, yo is correct, just expand that formula with your calculator
each one is 5% bigger than pevious
each one=previous+previous*5%
each one=previous*1+previous*0.05
each one=previous*(1+0.05)
each one is 1.05 times of previous
so after n years, if today year size is P then

A=final size
so ya, after 18 years, n=18 so you get

A=2067.29 microliters
6 groups of 3 6 times 3 which equals 18
and 18 divided by 4 is 4.5 so it takes 5 cars.
