A manufacturer determines that x units of a product will be sold if the selling price is p= 450 – 0.025x dollars for each unit. If the production cost for x units is c = 600 + 20x, find the number of units that maximizes the profit.
Solve the system of equations by the Gauss-Jordan method. (Enter your answers as a comma-separated list. If the system is inconsistent, answer INCONSISTENT. If the system is dependent, parametrize the solutions in terms of the parameter t.)
x1 + x2 + x3 = ˆ’10
x1 + 2×2 + 2×3 = ˆ’15
x1 + 3×2 + 2×3 = ˆ’18
(x1, x2, x3) =
