In order to do this, you have to find your profit equation and then set it equal to 800, which is the profit you're seeking. when you subtract the cost from the revenue, the new equation (or the profit equation) is this:
p(x)= -.5x^2 + 60x -800. If you want your profit, p(x), to be $800, then you set your equation equal to 800 and solve it for x, the 2 values that will bring about that 800 profit. Those production levels, or values for x, are -22.5 and 142.5 Since you cannot have a negative production level, you need to produce 142.5 whatevers to make that profit.
Answer:
25
Step-by-step explanation:
x² is actually the same as x×x, which in this case, 5×5 = 25
area of painting = 13 * 17 = 221 square inches
221 * 0.30 = 66.30
the price would be $66.30
Hope this is simple enough!
