Avery invested $200 in an account paying an interest rate of 6 7/8%
Maslowich

Answer:

0.73 yrs

Step-by-step explanation:

if t is time in years

quarterly

600 = 200(1 + 0.06625/4)^4t

3 = (1 + 0.06625/4)^4t

ln3 = 4tln(1. + 06625/4)

t = ln3 / (4ln1.0165625)

t = 16.7198 yrs

continuously

600 = 200e^(0.06875t)

3 = e^(0.06875t)

ln3 = 0.06875t

t = ln3 / 0.06875

t = 15.9798 years

Δt = 16.7198 - 15.9798 = 0.73 yrs

In this situation you would use cos 
which is adjacent over hypotenuse 
so I take the cos50 and have it equal to 17 / x
 cos(50)= 17/x 
which is the same as ...
17 divided by cos(50) =x 
x=26.44730506
which rounds to 26.45 
So your answer would be A)

I hope everything makes sense, enjoy! <span />
