A movie theater has been charging $10.00 per person and selling about 500 tickets on a typical weeknight. After surveying their

kifflom [539]

Answer:

$p(x) = -0.01x + 15$

Step-by-step explanation:

Given

Let x represent the number of tickets, and p the charges

$(x_1,p_1) = (500,10)$

A reduction of 50c gives an increment of 50 tickets.

This gives:

$(x_2,p_2) = (500+50,10-0,5)$ ---- $50c = \$0.5$

$(x_2,p_2) = (550,9.5)$

Required

Determine the demand function

First, calculate the slope:

$m = \frac{p_2 - p_1}{x_2 - x_1}$

$m = \frac{9.5 - 10}{550-500}$

$m = \frac{-0.5}{50}$

$m = -0.01$

So, the equation is:

$p = m(x - x_1) + y_1$

$p = -0.01(x - 500) +10$

$p = -0.01x + 5 +10$

$p = -0.01x + 15$

Hence, the function is:

$p(x) = -0.01x + 15$

What is the result of adding these two equations?

andre [41]

Answer:

x=103/265 y=18/53

Step-by-step explanation:

5x -9y=1-----------(i)

-7x+2y=-5-----------(ii)

Multiplying eq 1 with 7 gives

35x-63y=7---------eq(iii)

Multiplying eq 2 with 5 gives

-35x+10y=-25--------eq(iv)

adding eq 3 qnd eq 4

35x-63y-35x+10y=7-25

-53y=-18

y=18/53--------eq5

Putting the value of y from eq 5 in eq 1

5x-9(18/53)=-5

5x- 162/53=-5

5x=-5 +162/53

5x= -265+162/53

5x=103/53

x=103/265

baherus [9]

Answer:

$Each =\pounds 1121$

Step-by-step explanation:

See comment for complete question.

Given

$Total = \pounds 8968$

$Projects = 8$

Required

Determine the amount allotted to each

From the question, we understand that each project gets each allocation.

So, the amount of each is:

$Each =\frac{Total}{Projects}$

$Each =\frac{\pounds 8968}{8}$

$Each =\pounds 1121$

<em>Each project gets £1121</em>
