CHAPTER X.

EQUATION OF PAYMENTS AND AVERAGE.

When several debts are due at different times, it is often desirable to find some time at which they may all be paid, without loss to either the debtor or the creditor. This time is called the AVERAGE, or EQUATED TIME, and the process by which it is found is the EQUATION OF PAY

MENTS.

EXAMPLE FOR THE BOARD.

A merchant owes $4.00, payable in 3 months; $6.00 payable in 6 months, and $2.00 payable in a year. At what time may he pay the whole, so that neither party shall lose any interest?

He may keep $12.00, as long as $1.00. Therefore, dividing 72mo. by 12, we obtain 6mo. for the equated time.

RULE.

Multiply each debt by the time in which it is payable, add all the products, and divide their sum by the sum of the debts.

This rule, which is universally adopted, is founded on the supposition that the interest of the money, which is not paid until after it is due, is equal to the discount of that which is paid before it is due. This is not strictly correct, but the difference is so trifling, that it does not materially affect the ordinary transactions of business.

1. I have three notes given by James Appleton; one of $75, payable in 30 days, one of $50, payable in 60/ days, and one of $500, payable in 90 days. What is the equated time for the payment of the whole?

2. A merchant sold goods, agreeing to receive of the amount in 3 months, in 6 months, and the rest in 9 months. At what time might the bill be settled by a single payment?

3. What is the equated time for the payment of $1000, of the sum being now due, in 3 months, and in 9 months? [The $250 now due has no time to run, and the product 250×0=0.]

4. What is the equated time for the payment of a debt, of which is now due, in 3 months, in 9 months, and the remainder in 15 months?

5. What is the equated time for the payment of three debts, one of $100, due in 8mo., one of $25, due in 11y., and one of $90, due in 2y.?

6. On a debt of $400, due in 9mo., a payment of $100 is made in 3mo. In what time should the remainder be paid?

7. I owe $40, payable now, $40 in 30 days, $20 in 60

days, and $100 in 120 days. What is the equated time for the payment of the whole?

8. Manson & Hill, of Liverpool, have given to Thomas Morton & Co. of New York, a note of £225 10s., payable x in 60 days; one of £196, payable in 60 days; one of £218 7s. 6d., payable in 90 days; and one of £300, payable in 120 days. At what time may the notes all be cancelled by a single payment?

9. On a debt of £1100, due in 9mo., a payment of £159 4s. is made in 3mo., and another of £300 in 41mo. What is the equated time for the payment of the balance?

By this rule we may obtain the average price of a number of ingredients of different value. The quantity of the several ingredients is substituted for the debts, and the price for the times.

10. A grocer mixes 10 pounds of tea, at 50 cents a pound, 12 pounds at 75 cents, and 16 pounds at 621 cents. What is the value of a pound of the mixture?

11. If 12 gallons of water are mixed with 9 gallons of wine, at $1.00 per gallon, and 12 gallons at $1.50, what is the mixture worth per gallon?

12. Required the average length of 5 pieces of sheet. ing, measuring as follows: No. 1, 321yd.; No. 2, 311yd.; * No. 3, 331yd.; No. 4, 303yd.; No. 5, 34yd.

13. If I mix 3lb. of gold 22 carats fine, 5lb. 20 carats fine, 8lb. 24 carats fine, 107b. 23 carats fine, and 2lb. of alloy, what will be the fineness of the mixture? [A carat is 24 Pure gold is 24 carats fine. Alloy is counted of no value.]

14. A grocer mixed 18 gallons of molasses, at 25 cents a gallon, with 20 gallons at 30 cents, 24 gallons at 40 cents, and 5 gallons of water. At what price per gallon must he sell the mixture to gain 25 per cent. ?

15. If the thermometer stands from 6 to 9 at 68°, from 9 to 11 at 70, from 11 to 1 at 73°, from 1 to 4 at 77°, and from 4 to 6 at 76°, what is the average temperature of the 12 hours?

16. The following charges are made against Walton & Morris, each payable in 8 months, viz: Jan. 25, $1643. 50; Feb. 1, $900; Feb. 16, $1131.25; Feb. 28, $241.
