Step-by-step explanation:
EAR = (1 + APR/T)∧T−1
1. With 9.4 % quarterly compounding
EAR = (1 + 0.094/4)∧4 - 1 = 1.0235∧4 - 1 = 1.0973 - 1 = 0.0973
Quarterly EAR = 9.73 %
2. With 18.4% monthly compounding
EAR = (1 + 0.184/12)∧12 - 1 = 1.01533^12 - 1 = 1.2003 - 1 = 0.2003
Monthly EAR = 20.03 %
3. With 14.4% daily compounding
14.4/365 = 0.0394%
EAR = (1 + 0.144/365)∧365 - 1 = 1.000394^365 - 1 = 1.1546 - 1 = 0.1546
Daily EAR = 15.46 %
4. With 11.4% infinite compounding
EAR = (1 + 0.114/10000)∧10000 - 1 = 1.0000114∧10000 - 1 = 1.12075 - 1
= 0.1207
Infinite EAR = 12.07%
