Answer:

13.7%

Step-by-step explanation:

Nominal interest rate = $(\sqrt[m]{1 + effective annual interest rate} - 1 \ ) m$

where m = number of compounding = 12

( $\sqrt[12]{1.146}$ - 1 ) x 12 = 0.137054 = 13.7%

To round to one decimal place means that there should be only one figure after the decimal place.
