How long does it take a 2700 dollar investment compounded monthly at 9% to make 500 dollars

valina [46]

Answer:

23 months

Also please note that it's everytime ^t/12 not (^t)/12

Step-by-step explanation:

Principal (P) = $2700

rate = 9%

t = ?

Amount = $P(1+\frac{r}{100} )^(t/12)$

Amount = 2700 +500 = $3200

So substituting all our values we get :

$3200 = 2700(1+\frac{9}{100})^(t/12)\\ 3200=2700(1+0.09)^(t/12)\\3200 = 2700(1.09)^(t/12)\\\frac{3200}{2700} =1.09^(t/12)$

So we use log to solve for t :

$t/12=log_{1.09} (\frac{3200}{2700})\\$

Solving this using a calculator we get:

1.9714966193*12

=23 months

NEED HELP ASAP! WILL MARK BRAINLIEST!

snow_tiger [21]

The answer would be 30 since for 180 pounds and 60 feet you would need to divide 180 by 60 to get the unit rate for the pressure and then multiply by 10 which would get you 30. Correct me if I’m wrong. Hope it helps :)
