Answer:
17.5%
Explanation:
Effective annual rate is a yearly rate of return which includes the compounding effect. APR is the simple rate of return which is being paid on the principal amount that is being invested.
Formula for Effective Interest rate
EAR = ( 1 + APR/n )^n -1
0.18974 = ( 1 + APR/12 )^12 -1
0.18974 + 1 = ( 1 + APR/12 )^12
1.18974 = ( 1 + APR/12 )^12
(1.18974)1/12 = (( 1 + APR/12 )^12 )1/12
1.0146 = 1 + APR/12
1.0146 - 1 = APR / 12
0.0146 = APR / 12
APR = 0.0146 x 12
APR = 0.175 = 17.5%
