EXAMPLE, What is the interest on $S4.|for 06 days? Opposite 84 we find the number 2333 This multiplied by the|number of days 66 153978 Reject the three right hand figures of the product, and you have the correct interest in cents— 1.53. What is t lie interest on $947 for 93 days? ( ipposite 900 we find 25000 Opposite 47 we find 1305 Adding gives us — This multiplied by 26205 93 2446365 Rejecting the three right hand figures of the product, gives us a correct amount- 24.46. What is t lie interest on $S,728 for 123 days, at 10 per cent? Opposite 8000 we find 222222 Opposite 700 we find 19444 Opposite 28 we find 777 Adding gives us 242443 Multiply by number of days 123 29820489 Rejecting three right hand figures of the product, gives us $298.20— the interest. «i®_The merit of this brief table is its simplicity. There are niidecimals, no fractions, no divisions, and the rule is invar- iable. Out off /ram the final product the three right hand figures , and you have the interest Clinics *J 0P /9 71 Robinson & Bro, Sliarptown. Md. G E Hawley, Yankton, D. T. G T Wiki, Canton, Mo.
