Answer:
option c boo if it's for plata
Exponential growth is
F=P(1+r)^t
F=future amount
P=present amount
r=rate
t=time in years
rate=2%=0.02
therefor the equation is
f(x)=23,000(1+0.02)^x
f(x)=23,000(1.02)^x
where x=time in years from 2012
7(x-2) +3x=46
7x-14+3x=46
10x-14=46
10x=60
X=6
30:45
6:9
10:15
I believe that’s it,
hope this helps
