The equation that can be used to represent the number of albums at which the profit would be equal for the two methods of selling her album is -0.03x² + 4x + 6000 = 0
How to solve equations in the form of no quadratic
- x = the number of albums sold
- y = the profit in dollars,
Method 1, y = -0.05x² + 12x - 8000
Method 2, y = -0.02x² + 8x - 2000
- Equation both equations
-0.05x²2 + 12x - 8000 = -0.02x²2 + 8x - 2000
- 0.05x² + 0.02x² + 12x - 8x - 8000 + 2000 = 0
-0.03x² + 4x - 6000 = 0
where,
a = -0.03
b = 4
c = -600
