Answer:
p(4) = $10.69
p(14) = $20.79
p(14) - p(4) = $10.10
p( 14) - p(4)/14-4, and interpret this result
$1.01 This means that during this interval of 10 years, ticket prices increased, on average, $1.01 a year.
Step-by-step explanation:
The average ticket price for a baseball game, in p years after 1991, can be modeled by the following equation:
[tex]p(x) = 0.03x^{2} + 0.47x + 8.33[/tex]
Find p(4).
[tex]p(4) = 0.03*4^{2} + 0.47*4 + 8.33 = 10.69[/tex]
Find p(14).
[tex]p(4) = 0.03*14^{2} + 0.47*14 + 8.33 = 20.79[/tex]
Find p( 14) - p(4).
20.79 - 10.69 = 10.10
Find p( 14) - p(4)/14-4, and interpret this result.
10.10/10 = 1.01.
This is the yearly average rate that the ticket price changed during this interval. This means that during this interval of 10 years, ticket prices increased, on average, $1.01 a year.
