a. 0.3225% per month

b. 3.9393874%

c. $1,879.80

Explanation:

a. 3.87%/12

= 3.87/100

= 0.0387/12

= 0.003225 * 100

= 0.3225% per month

b. (1 +.003225) ^12 - 1

= 1.039393874 - 1 =.039393874

= 3.9393874% (note how this is slightly larger than 3.87%)

c. The formula to solve this is P r / (1 - ((1 / (1+r)) ^n)

$400,000 *.003225 / (1 - ((1 / (1+.003225)) ^360) = $1,879.80
