Answer:

916.57 pounds

Step-by-step explanation:

Cost of beef = 7.53 pounds × 9

= 67.77 pounds

Cost of potatoes = 6.45 pounds × 9

= 58.05 pounds

Cost of carrots = 6.23 pounds × 4

= 24.92 pounds

Total cost = 67.77 pounds + 58.05 pounds + 24.92 pounds

= 150.74 pounds

Total revenue = 27 meals × 39.53 pounds

= 1067.31 pounds

Total profits = Total revenue - Total cost

= 1067.31 pounds - 150.74 pounds

= 916.57 pounds

<h3>Answer: Choice A) 3.5</h3>

Work Shown:

The point (8,28) is the furthest to the right on the graph. We have x = 8 and y = 28 pair up here. Divide the y over the x

y/x = 28/8 = 3.5

side note: the tickmarks on the y axis go up by 4 each time

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.
