The first equation in the following system gives a company's income, in dollars, for selling x baseball caps. the second equation gives the cost of making x baseball caps. y = 8x y = -0.01 x2 + 4x + 3,200

Given that the equation y=8x models the income of the company in dollars and the equation y=-0.01x²+4x+3200 models the cost of making x baseball caps. The profit of making x caps will be given by:
Profit=(total income)-(total cost)
=8x-(-0.01x²+4x+3200)
=8x+0.01x²-4x-3200
=0.01x²+4x-3200
Hence the answer is, profit will be given by:
y(x)=0.01x²+4x-3200

Is 8.50 an answer or no? ?
