4/7=0.571428

5/7=0.714285

6/7=0.857142

Step-by-step explanation:

1/7 = 0.142857

2/7=0.285714

3/7=1/7+2/7

3/7=0.142857+0.285714

3/7=0.428571

3/7=3(1/7)

3/7=3(0.142857)

3/7=0.428571

4/7=2(2/7)

4/7=2(0.285714)

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
