This is an an example of simultaneous equations, no single equation can give us the answer. Were going to use the substitution method. We will call this equation 1: 2x + y = 18, and this equation 2: x-y=6...
Differentiating with respect to x gives:3x^2 -y^2- x 2y(dy/dx) = 03x^2 -y^2 = x2y(dy/dx)dy/dx = (3x^2 - y^2)/2xy
5.54 x100 = 554 554 x 27 = 3878 + 11080 = 1495814958 / 100 = 149.58 149.58 < 150 Therefore Steve does have the money to buy all 27 plants.
