**Investment Growth Problem**

Suppose that $13,000 is invested in a bond fund and the account grows to $14,757.69 in 5 years.

**Part 1 of 2**

(a) Use the model \( A = Pe^{rt} \) to determine the average rate of return under continuous compounding. Round to the nearest tenth of a percent. Avoid rounding in intermediate steps.

The average rate of return under continuous compounding is approximately _____ %. 

*Note: The problem involves calculating the continuous compounding rate of return using the exponential growth formula, where \( A \) is the final amount, \( P \) is the principal amount, \( r \) is the rate of return, and \( t \) is the time in years.*
