Explanation:

Step1: Identify compound interest formula

Assuming annual compounding (standard for such problems), the formula is:
$$A = P(1 + r)^t$$
Where:

  • $A$ = final amount
  • $P = 3400$ (principal)
  • $r = 0.075$ (annual interest rate)
  • $t = 17$ (time in years)

Step2: Substitute values into formula

$$A = 3400(1 + 0.075)^{17}$$

Step3: Calculate the growth factor

First compute $1.075^{17} \approx 3.497608$

Step4: Multiply by principal

$$A = 3400 \times 3.497608 \approx 11891.87$$

Answer:

11891.87 dollars
