For this case we have the following inequations:
 1.5x-1> 6.5
 7x + 3 <-25
 Clearing x from each one we have:
 For 1.5x-1> 6.5:
 1.5x> 6.5 + 1
 1.5x> 7.5
 x> 7.5 / 1.5
 x> 5
 For 7x + 3 <-25:
 7x <-25-3
 7x <-28
 x <-28/7
 x <-4
 The solution set is:
 (inf, -4) U (5, inf)

The Better Baby Buggy Co. has just come out with a new model, the Turbo. The market research department predicts that the demand
dlinn [17]

Answer:

$68

Step-by-step explanation:

We have been given the demand equation for Turbos as q=-4p+544, where q is the number of buggies the company can sell in a month if the price is $p per buggy.

Let us find revenue function by multiplying price of p units by demand function as:

Revenue function: pq=p(-4p+544)

pq=-4p^2+544p

Since revenue function is a downward opening parabola, so its maximum point will be vertex.

Let us find x-coordinate of vertex using formula \frac{-b}{2a}.

\frac{-b}{2a}=\frac{-544}{2\times -4}

\frac{-b}{2a}=\frac{-544}{-8}

\frac{-b}{2a}=68

The maximum revenue would be the y-coordinate of vertex.

Let us substitute x=68 in revenue formula.

pq=-4(68)^2+544(68)

pq=-4*4624+544(68)

pq=-18496+36992

pq=18496

Therefore, the company should sell each buggy for $68 to get the maximum revenue of $18,496.
