c. How long will it take the fund she invested in to be worth $7,000?

a.$609.5

b.$122.5

c.14.16 years

d.$ 180.09  

Step-by-step explanation:

The cost of the shares=(850*$8.40)+$14=$7154

proceeds from sale of shares=(850*$9.15)-$14=$7763.5

Gain on sale of shares=$7763.5 -$7154=$609.5

The interest receivable semiannually=$3500*7%*6/12=$122.5

The length of time it would take for the fund to worth $7,000 can be derived from future value formula

FV=PV*(1+r)^n

FV is $7000

PV is $4,300

r is the growth rate per year of 3.5%

n is the not known

7000=4300*(1+0.035)^n

7000/4300=1.035^n

1.627906977 =1.035^n

take log of both sides

ln 1.627906977 =n ln1.035

n=ln 1.627906977 / ln 1.035=14.16 years

biweekly gross income=($50,850/12*2)=$2118.75

(4%+4.5%)*2118.75 =$ 180.09
