The cost of a cd after 6 year is =$ 15.12
Step-by-step explanation:
The present cost of the cd is $11.95 and inflation rate 4%
P = $11.95 , r = 4% and n = 6 years
The cost of a cd after 6 year is =
=$ 
=$ 15.12
Hi bestie lol i’m failing math too and use this app as a lil cheat :)
The time it will take the principal to grow to the desired amount is 0.7 years
Using the compound interest formula :
A = P(1 + r/n)^(nt)
A = final amount = 225,000
P = principal = 180,000
r = rate = 3.12%
n = Number of compounding times per period = 12(monthly)
t = time
225000 = 180000(1 + (0.0312 /12))^(12t)
Divide both sides by 180000
225000/180000 = (1 + (0.0312 /12))^(12t)
1.25 = 1.026^12t
Take the log of both sides
0.0969100 = 0.0111473 × 12t
0.0969100 = 0.1337676t
Divide both sides by 0.1337676 to isolate t
0.0969100 / 0.1337676 = t
0.7244 years
0.7 years
It will take 0.7 years for the amount to grow
