A baseball team plays in a stadium that holds 56,000 spectators. With ticket prices at $10, the average attendance had been 16,000. When ticket prices were lowered to $8, the average attendance rose to 24,000. (a) Find the demand function (price p as a function of attendance x), assuming it to be linear. p(x)

Respuesta :

Answer:[tex]P=\frac{x}{16000}+6.5[/tex]

Step-by-step explanation:

Given

Spectator or attendance [tex](x)=56,000[/tex]

Price [tex]P=\$ 10[/tex]

When ticket price lowered by [tex]P=\$ 8[/tex]

attendance [tex](x)=24,000[/tex]

Suppose they follow a linear relation then

[tex]P=mx+C[/tex]

where [tex]C=constant[/tex]

for [tex]x=56,000[/tex]

[tex]10=56,000m+C\ldots (i)[/tex]

For [tex]x=24,000[/tex]

[tex]8=24,000+C\ldots (ii)[/tex]

From (i) and (ii) we get

[tex]2=32000m[/tex]

[tex]m=\frac{1}{16000}[/tex]

substitute the value of m to get [tex]C[/tex]

[tex]10=56,000\times \frac{1}{16000}+C[/tex]

[tex]C=6.5[/tex]

Therefore the required equation becomes

[tex]P=\frac{x}{16000}+6.5[/tex]
