content: Manufacturers of adding and calculating machines distributed a variety of printed mathematical tables for users of their products. This example, printed in black on white cardboard, was prepared by Felt & Tarrant Manufacturing Company of Chicago, makers of the Comptometer adding machine. It was their Form No. 4 and lists the net result as a decimal of taking off two discounts in percent on an item sold. For example, the table indicates that if an item was selling at a 40% discount and then had an additional 10% discount on the price, the net price would be .54 times the original price. It was for use with a Comptometer. The form shows a Model J Comptometer, a machine produced in the late 1920s and early 1930s. Hence the date assigned.
