Step 1 :Given that the principal amount (P) is $4000, the final amount (A) is $5372, the annual interest rate (r) is 7% or 0.07 in decimal, and the interest is compounded quarterly (n=4).
Step 2 :We can use the formula for compound interest, rearranged to solve for time (t): \(t = \frac{\log(\frac{A}{P})}{n \cdot \log(1 + \frac{r}{n})}\)
Step 3 :Substitute the given values into the formula: \(t = \frac{\log(\frac{5372}{4000})}{4 \cdot \log(1 + \frac{0.07}{4})}\)
Step 4 :Solving the equation gives us \(t \approx 4.249698331550322\)
Step 5 :Rounding to the nearest hundredth, we get \(t \approx 4.25\)
Step 6 :Final Answer: The time it will take for the account to grow to $5372 is approximately \(\boxed{4.25}\) years.
