Question: Add the new 'a' value back into each equation: 120 = 30(-0.833) + b = 144.98 100 = 54(-0.833) + b = 144.98 The price-demand


Add the new 'a' value back into each equation: 120 = 30(-0.833) + b = 144.98 100 = 54(-0.833) + b = 144.98 The price-demand function has now been solved to: p = -0.833 + 144.98 Total Revenue function: TR = (-0.833q + 144.98)q = -0.833q2 + 144.98q Profit function: TC = 99q - 360 TR - TC = (-0.833 q2 + 144.98q) - (99q -360) = (-0.833q2 + 144.98) - (99q + 360) = -0.833q2 - 45.98q - 360 p = -0.833q2 - 45.98q - 360 Break-even point: = -0.833q2 - 45.98q - 360 = 0 -45.98+45.98--(4x-0.833x-360) = -3.167 + 10161 2(-0.833)
