Answer:
Correct option: (A) 43.48% fall in the price of a ticket.
Step-by-step explanation:
The price elasticity of demand is defined as the percent change in quantity demanded to the percent change in the price.

Given:
Price elasticity of demand = 0.23
% change in quantity demanded = 10
Compute the % change in price as follows:

Thus, a 10 percent increase in attendance can be explained by a 43.48% fall in the price of a ticket.
Answer:
g=15 3(15)+20, g=10 3(10)+20, g=38 3(38), g=20 3(20)+20
Step-by-step explanation:
Answer:
3. 0
4. n = -2
Step-by-step explanation:
I haven't taken pre-calc but this looks a lot like algebra.
For #3, just plug in -2 for the x values, so:
x^2 + 4x +4
(-2)^2 + 4(-2) + 4
= 4 - 8 + 4
= 0
For #4, move the variables to one side and solve( im not sure what the pi is for tho, or is that a n?):
5n + 6 = -3n - 10
add 3n to both sides
8n + 6 = -10
subtract 6 from both sides
8n = -16
divide both sides by 8
n = -2
