p=-0.05x+502 (0(less than or equal too)x(less than or equal too)12,000)

where p denotes the wholesale unit price in dollars and x denotes the quantity demanded. The weekly total cost function associated with manufacturing these sets is given by

c(x)=0.000003x^3-0.05x^2+400x+80,000

where C(x) denotes the total cost incurred in producing x sets. Find the level of production that will yield a maximum profit for the manufacturer. Hint: Use the quadratic formula. (Round your answer to the nearest whole number.)

**Steve**, Thursday, November 15, 2012 at 10:12amprofit = revenue - cost

revenue = price * quantity

profit is thus

y = x(-0.05x+502) - (0.000003x^3-

0.05x^2+400x+80000)

y = 0.000003x^3 + 102x + 80000

y' = -0.000009x^2 + 102

y'=0 when x = 3366
