Mrs Chen will make a profit which is 12% of the original price, if she sells the necklace at $4144. What will be her profit if she sells the necklace at $4250?

Mrs Lim will make a profit which is 19% of the import price if she sells the necklace at $4165. What will be her profit if she sells the necklace at $4270 and the import price of the necklace remains constant?

The revenue and cost functions, both in dollars, for the production and sale of x TVs are given as R(x) = 160x − 0.8x2 and C(x) = 3,240 + 15x, respectively.(a)Find the value(s) of x where the graph of R(x) has a horizontal tangent line with correct units. (Enter your answers as a comma-separated list. Round your answers to the nearest integer. If an answer does not exist, enter DNE.)x = 100   (b)Find the profit function in terms of x. (Note: Profit is revenue minus costs.)P(x) = −.8x2+145x−3240 (c)Find the value(s) of x where the graph of P(x) has a horizontal tangent line with correct units.
