Answer:
e. 1.88%
Explanation:
EAR = (1+APR/m)^m. M means compounding periods
For Southwestern Bank
EAR = (1 + 0.069/12)^12 - 1
EAR = 1.00575^12 - 1
EAR = 1.0712245 - 1
EAR = 0.0712245
EAR = 7.12%
So, the difference between the effective annual rate charged by Woodburn versus the rate charged by Southwestern is 1.88% (9% - 7.12%)
