The revenue, in dollars, of a company that manufactures televisions can be modeled by the polynomial 3x²+180x . The cost, in dol
tresset_1 [31]

We use the profit concept, and doing this, it is found that if 150 televisions are sold, the profit is $50,700.

-------------------------------------------

Profit is given by revenue subtracted by cost.

In this question:

  • Revenue: R(x) = 3x^2 + 180x
  • Cost: C(x) = 3x^2 - 160x + 300

Thus, the profit of selling x televisions is:

P(x) = R(x) - C(x)

P(x) = 3x^2 + 180x - (3x^2 - 160x + 300)

P(x) = 3x^2 + 180x - 3x^2 + 160x - 300

P(x) = 340x - 300

-------------------------------------------

For 150 televisions, we have P(150), so:

P(150) = 340(150) - 300 = 50700

If 150 televisions are sold, the profit is $50,700.

2(2/5) divided 2(-1/5)

we do PEMDAS meaning parenthesis first

2(2/5) = 4/5(calculator)

or

2/1x2/5=4/5

now

2/1x-1/5=-2/5

now we do division

4/5/-2/5 we get -2

-2
