*Each percentage is computed by dividing the number for that item by net sales. For instance, sales salaries last year (Fig. 12-2) were $150,000. Dividing that by net sales of $1.247 million gives us 0.120 or the 12.0 percent listed for sales salaries in Fig. 12-3. For the prior year, the computation is $140,000 ÷ $1.125 million, or 12.4 percent.
