A concession stand at a sports stadium sells 600 bags of peanuts (each game) if the price of each bag is $4.00. For each $0.25 i

grin007 [14]

Answer:

Price = $4.50

Maximum revenue = $2,430

Step-by-step explanation:

The concession stand sells 600 bags of peanut at $4.00 (600, $4.00).

If there is a $1 increase in price, the number of bags old will decrease by 120, which mens that 480 bags of peanuts will be sold at $5.00 (480, $5.00).

Tracing a linear relationship between price and quantity sold with the two given points:

$m = \frac{5-4}{480-600}\\ m=-\frac{1}{120}$

$P - P_0=m*(Q-Q_0)\\P-4.00=-\frac{1}{120} (Q-600)\\P= -\frac{1}{120}Q +9$

The revenue function is given by the price multiplied by the quantity sold:

$R=Q*P= (-\frac{1}{120}Q +9)*Q\\R=-\frac{1}{120}Q^2 +9Q$

The value of 'Q' for which the derivate of the revenue function is zero, is the output level for which revenue is maximum:

$R'=0=-\frac{2}{120}Q+9\\Q_{max} = 540\\P_{max} = -\frac{540}{120} +9\\P_{max} =\$4.50$

The total revenue of 540 units at $4.50 per unit is:

$R = \$4.50*540\\R=\$2,430$

Slope -8 and y intercept 7

max2010maxim [7]

Answer:

The equation of Line is y = - 8x + 7

Step-by-step explanation:

Given as :

The slop of line is - 8

And The y intercept is 7

As the equation of line is y = mx + c

For y intercept , x = 0

So, With y intercept and slop ,

7 = (-8)× (0)+ c

Or, c = 7

So the equation of line is

y = mx + c

I.e y = ( - 8 ) x + 7

Hence The equation of Line is y = - 8x + 7 Answer
