Figure 1
The horizontal axis is labeled “k subscript 1”, and ranges from 2.4 to 3.0 in increments of 0.1 units. The vertical axis is labeled “Eta superscript D subscript m plus Eta superscript D subscript r”, and ranges from 0.40 to 0.50 in increments of 0.02 units. The three distinct lines represent different scenarios. The first line represents “Gamma equals 0.9”, starts near the coordinate pair 2.4, 0.41 and gradually decreases, passing through 2.6, 0.408 and 2.8, 0.406, to end near 3.0, 0.405. The second line represents “Gamma equals 1.0”, starts near the coordinate pair 2.4, 0.43 and gradually decreases, passing through 2.6, 0.42 and 2.8, 0.415, to end near 3.0, 0.41. The third line represents “Gamma equals 1.1”, starts near the coordinate pair 2.4, 0.51 and decreases more steeply, passing through 2.6, 0.46 and 2.8, 0.438, to end near 3.0, 0.425. Note: All numerical values are approximated.Impact of and on profit
