Deposited $2,500 into an account that accrues interest monthly. she made no additional deposits or withdrawals. after 2 years, claire had $2,762.35 in thr account. what is the annual interest rate of the account

A) exponent = log (total/principal) / n*years
exp = log (2,762.35 / 2,500) / 12 * 2
exp = log ( 1.10494 ) / 24
exp = 0.04333869578 / 24
exp = 0.001805779
b) rate = (10^exp -1) * n
b) rate = ( 10^0.001805779 -1) * 24

b) rate = (1.0041666161 -1) * 12

b) rate = (.0041666161 ) * 12

b) rate = 0.0499993932
Which equals 4.99993932%
