When the price is an even part of a pound-Find the value of the given quantity at one pound per yard, &c. and divide it by that even part, and the quotient will be the answer in pounds. EXAMPLES. What will 129 yards cost at 2s. 6d. per yard? s. d. 26 Ans. £16 38. 9d. value at 2s. 6d. per yard. Yds. s. d. 123 at 10 0 per yard. 687 at 50 2114 at 4 0 543 at 6 8 127 at 34 461 at 1 8 £. s. d. NOTE. When the price is pounds only, the given quan tity multiplied thereby, will be the answer. EXAMPLES.-11 tons of hay at 47. per ton. Thus 11 4 Ans. £44 CASE III. When the given price is any number of shillings under 20. 1 When the shillings are an even number, multiply the quantity by half the number of shillings, and double the first figure of the product for shillings; and the rest of the product will be pounds. 2. If the shillings be odd, multiply the quantity by the whole number of shillings, and the product will be the answer in shillings, which reduce to pounds. When the given price is pence, or pence and farthings, and not an even part of a shilling--Find the value of the given quantity at 1s. per yard, &c. which divide by the greatest even part of a shilling contained in the given price, and take parts of the quotient for the remainder of the price, and the sum of these several quotients will be the answer in shillings, &c. which reduce to pounds. EXAMPLES. What will 245 lb. of raisins come to, at 92d. per lb? Ans. £9 19 03 value of the whole at 9ad. per lb. When the price is shillings, pence and farthings, and not the aliquot part of a pound-Multiply the given quantity by the shillings, and take parts for the pence and farthings, as in the foregoing cases, and add them together; the sum will be the answer in shillings. EXAMPLES. 1. What will 246 yds. of velvet come to, at 7s. 3d. per yard? 3d. S d. 246 0 value of 246 yards at 1s. per. yd. 7 1722 0 value of do. at 7s. per yard. 2,0)178, 3 6 · Ans. £89 3 6 value of do. at 7s. per yard. When the price and quantity given arc of several denominations--Multiply the price by the integers in the given quantity, and take parts for the rest from the price of an integer; which added together will be the answer This is applicable to Federal Money. TARE and Tret are practical Rules for deducting certain allowances which are made by merchants, in buying and selling goods, &c. by weight; in which are noticed the following particulars : 1. Gross Weight, which is the whole weight of any sort of goods, together with the box, cask, or bag, &c. which contains them. 2. Tare, which is an allowance made to the buyer, for the weight of the box, cask, or bag, &c. which contains the goods bought, and is either at so much per box, &c.—or at so much per cwt. or at so much in the whole gross weight. 3. Tre', which is an allowance of 4 lb. on every 104 lb. for waste, dust, &c. 4. Cloff, which is an allowance made of 2 lb. upon every 3 cwt. 5. Suttle, is what remains after one or two allowances have been deducted. CASE I. When the question is an Invoice-Add the gross weights into one sum and the tares into another; then subtract the total tare from the whole gross, and the remainder will be the neat weight. EXAMPLES. 1. What is the neat weight of 4 hogsheads of Tobacco, marked with the gross weight as follows: 2. What is the neat weight of 4 barrels of Indigo, No. When the tare is at so much per box, cask, hag, &c.--Multiply the tare of 1 by the number of bags, bales, &c. the product is the whole tare, which subtract from the gross, and the remainder will be the neat weight. EXAMPLES. 1. In 4 hhds. of sugar, each weighing 10 cwt. 1q 1316 gross; tare 75lb. per hhd. how much neat? |
