Respuesta :

apologiabiology
ok, expnential growth

[tex]F=A(1+r)^t[/tex]
F=final amount
A=initial amount
r=growth rate iin decimal form
t=time in years elapsed


so given
A=6.25 million
r=3.22%=0.0322
t=2018-2012=6

so
[tex]F=6.26(1+0.0322)^6[/tex]
[tex]F=7.57[/tex]

so it will be about 7.57 million in 2018
