8.87%

2. What is the effective annual rate (EAR) of the mortgage at 8.5% APR with weekly payments? nothing% (Round to two decimal places.)

8.86%

Explanation:

1.

APR = 8.5%

Weekly Payment

Number of years = 20

m = 52 x 20 = 1040

EAR = ( 1 + ( 0.085 / 1040 )^1040)-1

EAR = 0.0887

EAR = 8.87%

2.

APR = 8.5%

Weekly Payment

Number of years = 1

m = 52 x 1 = 52

EAR = ( 1 + ( 0.085 / 52 )^52 ) - 1

EAR = 0.0886

EAR = 8.86%
