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

$A=P(1.05)^n$

A=final size

so ya, after 18 years, n=18 so you get

$A=859(1.05)^{18}$

A=2067.29 microliters
