Step-by-step explanation:

<u>Step 1: Define</u>

7a + 42 + 8 < -10 + 9a - 64a

<u>Step 2: Solve for </u><em><u>a</u></em>

  1. Combine like terms (a):                                                                                    7a + 42 + 8 < -10 - 55a
  2. Combine like terms:                                                                                         7a + 50 < -10 - 55a
  3. [Addition Property of Equality] Add 55a on both sides:                                62a + 50 < -10
  4. [Subtraction Property of Equality] Subtract 50 on both sides:                      62a < -60
  5. [Division Property of Equality] Divide 62 on both sides:                               a < -30/31

Here we see any number <em>a</em> less than -30/31 would work as a solution to the inequality.

The profits in hundreds of dollars, P(c), that a company can make from a product is modeled by a function of the price, c, they
Jobisdone [24]
The maximum profit is the y-coordinate of the vertex of the parabola represented by the equation.

P(c)=-20c^2+320c+5120 \\ \\&#10;a=-20 \\&#10;b=320 \\ \\&#10;\hbox{the vertex } (h,k): \\&#10;h=\frac{-b}{2a}=\frac{-320}{2 \times (-20)}=\frac{-320}{-40}=8 \\&#10;k=f(h)=f(8)=-20 \times 8^2+320 \times 8+5120= \\&#10;=-1280+2560+5120=6400

The maximum value is 6400, but the profit is given in hundreds of dollars, so multiply the value by 100.

The maximum profit the company can make is $640,000.
