Answer
Explanation:
Step1: Substitute x = 100 into each equation
- For $y=-1.026x^{2}+1016.402x - 162075$: $y=-1.026\times(100)^{2}+1016.402\times100 - 162075$ $y=-10260+101640.2 - 162075=-70494.8$
- For $y=-1.036x^{2}+1024.771x - 163710$: $y=-1.036\times(100)^{2}+1024.771\times100 - 163710$ $y=-10360+102477.1 - 163710=-71592.9$
- For $y = 298.214x-66317.667$: $y=298.214\times100 - 66317.667=29821.4 - 66317.667=-36496.267$
- For $y = 196.2x-18710$: $y=196.2\times100 - 18710=19620 - 18710 = 910$ (far - off)
Step2: Substitute x = 200 into each equation
- For $y=-1.026x^{2}+1016.402x - 162075$: $y=-1.026\times(200)^{2}+1016.402\times200 - 162075$ $y=-41040+203280.4 - 162075=10165.4$
- For $y=-1.036x^{2}+1024.771x - 163710$: $y=-1.036\times(200)^{2}+1024.771\times200 - 163710$ $y=-41440+204954.2 - 163710= - 396.8$
- For $y = 298.214x-66317.667$: $y=298.214\times200 - 66317.667=59642.8 - 66317.667=-6674.867$
- For $y = 196.2x-18710$: $y=196.2\times200 - 18710=39240 - 18710 = 20530$ (far - off)
Step3: Substitute x = 300 into each equation
- For $y=-1.026x^{2}+1016.402x - 162075$: $y=-1.026\times(300)^{2}+1016.402\times300 - 162075$ $y=-92340+304920.6 - 162075=50505.6$
- For $y=-1.036x^{2}+1024.771x - 163710$: $y=-1.036\times(300)^{2}+1024.771\times300 - 163710$ $y=-93240+307431.3 - 163710=50481.3$
- For $y = 298.214x-66317.667$: $y=298.214\times300 - 66317.667=89464.2 - 66317.667=23146.533$
- For $y = 196.2x-18710$: $y=196.2\times300 - 18710=58860 - 18710 = 40150$ (far - off)
Step4: Compare the results with the table values
By substituting more values of x from the table into the equations, we find that the equation $y=-1.036x^{2}+1024.771x - 163710$ gives values that are closest to the values in the profit - based on - number - of - items - produced table.
Answer:
$y=-1.036x^{2}+1024.771x - 163710$
