Finding the cost of telegrams and "night letters." This table gives the Western Union's day and night rates from New Orleans to the places named. The rate is the same in either direction. Thus, the day rate to Washington is 50-3, which means 50 cents for the first ten words and 3 cents for each additional word; while the standard night rate is 40 cents for the first ten words and 3 cents for each additional word. The special night rate for telegraphing "night letters" of 50 words (or less) is the same as the day rate on 10 words, and of the day rate for every 10 words (or less) over 50 words. Find the cost of sending from New Orleans: 1. A 16-word telegram to Boston at a day rate. 2. A 72-word "night letter" to Atlanta. 1. 60+6 x 4 = 84%. 2. 50+ 3x of 50% = 80%. 3. A 20-word telegram to New York at a day rate. 4. A 12-word message to Memphis, standard night rate. 5. A 19-word telegram to Jackson at a day rate. 6. A 55-word "night letter" to Austin. 7. A 65-word "night letter" to Chicago. 8. How much more will a 45-word telegram to Shreveport cost at a day rate than as a "night letter"? 9. Find the cost of a 60-word "night letter" to Jackson. 10. At $3 a chair, $24 will buy chairs. $24 will buy as many chairs as $3 is contained times in $24; $3 is contained in $24 8 times; therefore $24 will buy 8 chairs. //.

Why are the above called dry measures? 3. How many pints of corn will fill a quart measure? 4. What part of a quart is a pint? 5. How many quarts of oats will fill a peck measure? 6. What part of a peck is a quart? 7. How many pecks of wheat will fill a bushel measure? 8. What part of a bushel is a peck? pk. stands for "peck" or "pecks," and bu. for "bushel" or "bushels.” = Two pints equal one quart (2 pt. 1 qt.). Eight quarts equal one peck (8 qt. = 1 pk.). Four pecks equal one bushel (4 pk. = 1 bu.). 9. How many pints are there in 3 quarts? in 5 qt.? 10. How many quarts are there in 2 pecks? in 7 pk.? //. How many pecks are there in 4 bushels? in 9 bu.? 12. How many quarts are there in 8 pints? in 14 pt.? 13. How many pecks are there in 24 quarts? in 40 qt.? 14. How many bushels are there in 20 pecks? in 36 pk.? INEXACT DIVISION Dividing by subtracting. /. How many 4's are there in 14? 14-4=10; 10 − 4 = 6; 6 − 4 = 2. complete the following: What is the remainder? Then 14 contains 4 times, with a remainder 2. How many are 19-5-5-5? How many 5's are there, then, in 19, and how many ones over? 3. Find 217 by subtraction, 21 — 7 = 14, 14 — 7 = 7, 7—7 = 0; 21 — three 7's = 0; 21, therefore, contains 7 three times. 4. Find 336 by subtraction. 33-6=27, 27 five · 6 = 21, 21 − 6 = 15, 15 – 6 = 9, 9 − 6 = 3; 33 6's = 3; therefore 33 contains 6 five times with a remainder of 3; or 3365 and 3 over. Dividing by taking out multiples of the divisor. 1. Name the first ten multiples of 2; of 3; 4; 5; 6; 7; 8; 9. 2. Name the greatest multiple of 3 in 11; in 20; 28. 3. Name the greatest multiple of each of the numbers 4, 5, and 6 in 11; in 17; 23; 26; 33; 38; 41. 4. Name the greatest multiple of each of the numbers 7, 8, and 9 in 15; in 23; 29; 34; 39; 43; 47; 51; 57; 65. 5. Divide 37 by 8. Think: The greatest multiple of 8 in 37 is 32; 328 = 4, and 37-32 = 5, and say: 37 + 8 4 and 5 over. |
