Revenue from ticket sales: 4x(x+6)

Cost of band: 5x((x-4)

Profit: 160 (given in thousands)

The equation to determine profit is Revenue – Cost = Profit. Write the equation that explains the profit made last year. Be certain to combine like terms.

substitute the terms

[4x(x+6)] - [5x(x-4)] = 160,000

expand

4x^2 + 24x - 5x^2 + 20x = 160,000

combine like terms

-x^2 + 44x - 160,000 = 0
