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
Answer:
B=16 ounces
C=24 ounces
B=1/0.75=133%
Step-by-step explanation:
we have that
A≡0.25B (25%), if A=4 ounces then B=4/0.25 = 16 ounces
C=1.5B (150%), if B=16 ounces then C=1.5*(16 ounces) = 24 ounces
D≡xB (?%), if D=12 ounces then x=12/16 = 0.75 ≡ 75%, but xB≡D ⇒ B≡D/x →
B≡12(1/0.75)= B=12*(1.333)→ B≅133%D
