Answer :
The profit expression from selling x motorcycles expressed as a polynomial is : -0.003x² + 4x + 400000
The value of profit cab be found using the expression :
Profit = (Cost of production - Revenue)
Profit = (Cost of production - Revenue) Cost of production = 13x + 400000
Profit = (Cost of production - Revenue) Cost of production = 13x + 400000Revenue = 0.003x² + 9x
Profit = (13x + 400000) - (0.003x² + 9x)
Profit = 13x + 400000 - 0.003x² - 9x
Profit = 13x - 9x + 400000 - 0.003x²
Profit = 4x + 400000 - 0.003x²
The polynomial in simplified standard form can be expressed thus : -0.003x² + 4x + 400000
