When a note is discounted at a bank, the interest is taken at the time the note is given, and the interest is computed for 3 days more than the time specified in the note ; that is, if the note is given for 60 days, the interest is taken for 63 days ; for the law allows three days to the debtor, after the time has expired for payment, which are called days of grace. If, therefore, a note is given to the President and Directors of the Merrimack Bank for $ 100, to be paid in 60 days, the interest on the $ 100 is computed for 63, and taken from the sum of the note. So that the borrower receives only $ 98.95 for the note discounted. 1. What is the bank discount on $ 478, for 60 days ? Ans. $5.01+ 2. What is the bank discount on $ 780, for 30 days?

How much money should be received on a note of $ 1000, payable in 4 months, discounted at a bank, where the interest is 6 per cent. ? Ans. $ 979.50. Section 39. DISCOUNT. The object of discount is, to show what allowance should be made, when any sum of money is paid before it becomes due. The present worth of any sum is the principal, that must be put at interest, to amount to that sum in the given time. That is, $ 100 is the present worth of $ 106, due one year hence ; because $ 100 at 6 per cent. will amount to $ 106, and $ 6 is the discount. Therefore when the interest is 6 per cent. the present worth is ļos of the principal, and the discount is too of the principal ; and the same rule will hold good for any other per cent. 1. What is the present worth of $ 25.44, due one year hence ? Ans. $ 24.00. FIRST METHOD.
