A ship is valued at $16000; A owns , B1, C1, and the captain has the remaining share. The ship being injured in a storm, the repairs cost $2560; what is each one's share of the expense? ANALYSIS.—The value of the ship is $16000, and the loss $2560; $2560 -- 16000, or $ 2.56%= the loss on each dollar of capital invested; A owns of $16000=$3000, B owns of $16000= $4000, C owns of $16000=$8000, and the captain owns to of $16000= $1000. A's loss will be $ 25.696 3000=$480; B's loss, $ 2.560 x 4000= $640; C's loss, $ 2.560 X 8000= $1280; the captain's loss, $ 2560 x 1000 = $160. RULE. Make the whole gain or loss the numerator, and the whole capital the denominator of a fraction; multiply this fraction by each partner's capital, for his share of the gain or loss. 2.

ORAL EXERCISES. 1. Two men agree to build a wall for $20. The first man works 5 hours a day for 4 days, and the second man works 10 hours a day for 6 days; how should the money be divided between them? ANALYSIS.—The first man works 5 X 4= 20 hours; the second works 10 X 6=60 hours. The total number of hours' work is 60+ 20=80. If 80 hours' work is worth $20, each man is entitled to as many 80ths of $20 as he has worked hours. The first man works 20 hours, and earns , or of $20=$5; and the second man works 60 hours, and earns 60, or of $20=$15. 2. John and James agree to do a piece of work for $5. John works 2 hours a day for 5 days, and James works 4 hours a day for 10 days; how much should each receive? 3. Two men agree to carry 100 pounds of groceries 5 miles, for $1. One of them carries 50 pounds 4 miles, the other carries his 50 pounds the entire distance, and the remaining 50 pounds 1 mile. How should they divide $1 between them? WRITTEN EXERCISES. 1. A and B formed a partnership; A invests $2000 for 6 months, and B $1000 for 4 months; they gain $1600; how much is each man's share of the gain? A's capital = $2000 x 6 = $12000 for 1 month. ANALYSIS.—If A's capital was employed but 1 month, it would require 6 times $2000, or $12000, to gain the amount earned by $2000 in 6 months. If B's capital was employed but 1 month, it would require 4 times $1000, or $4000, to gain the amount earned by $1000 in 4 months. It would therefore require $16000 to gain as much in 1 month as $2000 in 6 months and $1000 in 4 months. If it requires $16000 of capital to gain $1600, $1 of capital will gain to voy of $1600 =$16600%. А’s $12000 will gain $16600.% 12000 = $1200; and B's $4000 will gain $ 16.00 X 4000 = $400. RULE. Multiply each partner's capital by the time it is employed. Make the sum of all these products the denominator of a fraction, and the total gain or loss the numerator. Multiply this fraction by the product of each partner's capital by the time it is employed, and the result will be each partner's share of the gain or loss. 2. Messrs. Brown and Jones formed a partnership for 2 years. Brown paid in $5000 at once, and Jones invested $6000 at the beginning of the second year. At the end of 18 months, Brown withdrew $1500.

Peter Carter enters a partnership six months after it is formed, and is required to invest sufficient capital to entitle him to i of the profits.

How should they divide a profit of $2060? EQUATION OF PAYMENTS. Equation of Payments is the process of finding the time when the payment of several sums of money due at different periods may be made at once, without loss of interest to debtor or creditor. The Equated Time is the date at which the sum of the debts may be paid without loss to either party. The Term of Credit is the time between the contracting of a debt, and the date when it becomes due. The Average Term of Credit is the time between the contracting of the first debt, and the equated time for the payment of them all. CASE I. To find the equated time when the terms of credit begin at the same date. ORAL EXERCISES. 1.
