Suppose that for a particular firm the only variable input into the production process is labor and that output equals zero when no workers are hired. in addition, suppose that when the firm hires 2 workers, the total cost of production is $100. when the firm hires 3 workers, the total cost of production is $120. in addition, assume that the variable cost per unit of labor is the same regardless of the number of units of labor that are hired. what is the firm's fixed cost?

Dr. sperry, a biologist, is using excel to track growth rates of different populations of bacteria. she has a very complex formula in one cell. it begins with “round”. dr. sperry would like to see exactly how excel’s calculation reached the final rounded value that she sees in the cell. what could dr. sperry do to best understand how the calculation was made? try different formulas on her own until she reaches the value shown in excel click on the evaluate formula button in the formulas tab and then click “step in” select the cell and then look at the formula in the formula field of the ribbon remove “round” from the formula in order to see the actual value before rounding
