EQUATION OF PAYMENTS.

SECTION XXII.

243. EQUATION OF PAYMENTS is the process of determining the average time for the payment of several sums, due at different periods.

244. RULE. Multiply each sum by the time before it becomes due, and divide the sum of the products by the sum of the payments.

OBS. 1. This rule has been considered by many as incorrect; but it is as correct as any rule founded upon simple interest can be.

If A owes B $200, $100 of which are to be paid in cash, and the other $100 to be paid in two years, the average time for the payment of the whole, according to the rule, would be one year, which is correct; for it is evident that if the money be paid according to the agreement, B would have at the end of two years $200, and the interest of $100 for two years. If the whole be paid in 1 year, B would have at the end of two years $200, and the interest of $200 for one year, which is the same as the interest of $100 for two years.

OBS. 2. If any sum be paid on the day from which the time is reckoned, it will have no product, but it must be added with the others in finding the sum of the payments.

OBS. 3. It is customary with merchants to add three days grace.

This rule is founded upon the principle that the use of $1 for any number of days is equivalent to the use of as many dollars as there are days for 1 day. Thus, the use of $1 for 150 days is equivalent to the use of $150 for 1 day.

1. A gentleman owes $150, payable in 60 days, $200, payable in 90 days, $400 in 120 days. At what time ought the whole to be paid at once?

At what time

245. To find the equated time of payments, when the sums due have different dates,

RULE. Find the time when each sum becomes due, and multiply each sum by the time between it and the first sum that is due, and divide the amount of the several products by the amount of the sums due.

OBS. As the time at which the first sum is due is the period from which the average time is computed, the first sum will have no product.

The principle of this rule is the same as that of the preceding, (ART. 244.)

12. What is the equated time for the payment of the following sums:

38 days from January 10, is February 17, the equated time.

EXAMPLES.

13. A merchant sold 484 barrels of rosin, as follows:

February 6, 4 months' cr., 35 barrels, @ $3.12).
