Tangent Company borrowed $100,000 from the bank signing an 8%, 6-month note on September 1. Principal and interest are payable to the bank on March 1. If the company prepares monthly financial statements, the adjusting entry that the company should make for interest on November 30, would be:

A) debit Interest Expense, $8,000; credit Interest Payable, $8,000.

B) debit Interest Expense, $667; credit Interest Payable, $667.

C) No adjusting entry is needed on November 30.

D) debit Interest Expense, $2,667; credit Interest Payable, $2,667.

(I know its B, but how would you work it out?)
