She will invest approximately $3,383.97

Explanation:

Formula for compound interest:

A = P (1 + r/n) ^nt

Where: A = Final amount

P = Principal amount

r = Interest rate

n = Number of compounding periods per year

t = Time period in years.

A = $8,000

P = Unknown

r = 7.30 percent = 7.3% = 0.073

n = semi annually = 2

t = 12 years

8,000 = P (1 + 0.073/2) ^2 (12)

8,000 = P (1 + 0.0365) ^24

8,000 = P (1.0365) ^24

8,000 = 2.364086453P

Divide both sides by the coefficient of P

8,000/2.364086453 = 2.364086453P/2.364086453

3,383.971001 = P

P ≈ $3,383.97

That is Elizabeth Brown will invest approximately $3,383.97 to achieve her goal
