Easy. You take 73.6 and subtract it by 59.2. 73.6 - 59.2 = 14.4. Explaination: Because there is 59.2 pounds of clay in all of 73.6, you subtract 73.6 by 59.2.
Blaine's Company: 103 x 6 = 618 William's Company: 1.2 x 105 = 126 Since William's Company made 126 x Blaine's company's 126 x 618 = 77868.00 (I am not sure if I did this right I tried though)
