Excerpt from book: CHAPTER III Problems Involving Decimal Fractions In the problems in this chapter the notion of decimal fractions is predominant. In some cases the pupils will be required to investigate the current prices of certain articles; e.g., groceries, as in sets I, II, III, and IV. Many of the problems in this chapter are similar to those in Chapter II, except that decimal fractions are used instead of common fractions. Hence the method of procedure in solving the problems will be the same. The following solutions of the problems in set XV are intended to be suggestive: 1. The assessed valuation = $1500 X .55 = $825. The no. of $100 = $825 -5- $100 = 8.25. .-. The tax = $2.84 X 8.25 = $23.43. 2. The amount for which the machine is insured = $1500 X .75 = $1125. The no. of $100 = $1125 + $100 = 11.25. .-. The premiu
...m = $.80 X 11.25 = $9. 3. The amount of depreciation = $1500 X .35 = $525. .-. The value would then be $1500 - $525 =$975. 4. The cost X the no. of hundredths 1UO $1500 X e no. of hundredths = $go() Theno.ofhundredths .-. The no. of hundredths = .60 X 100 = 60. 5. The number of acres purchased = $900 - $75 12. 6. The amount of rent per acre = $75 X .07 =$5.25. Using the current market price find the cost of: 1. 1 qt. of cranberries; 3 qts.; 1 gal. 2. 1 pk. of apples; pk.; 1 bu. 3. | bu. of sweet potatoes; pk.; 2 bu. 4. Ib. of coffee; |lb.; 2 Ibs. 5. ilb. of tea; 1 Ib.; Ib. 6. 2 Ibs. of corn meal; 5 Ibs.; 10 Ibs. 7. doz. bananas; doz. 8. 2 bars of laundry soap; 3; 5; 10. 9. 1 qt. navy beans; 2 qts.; 1 pk. 10. 5 Ibs. of granulated sugar; 25 Ibs. 11. 25 Ibs. of the best flour; 100 Ibs. 12. Ii Ibs. of beef steak; 3| Ibs.; 5 Ibs. Using the current market price find amount of: 1. Starch to b...
