Question

The local football team won the championship several years ago, and since then, ticket

prices have been increasing $4 per year. The year they won the championship, tickets were
$20. Write an explicit formula for a sequence that will model ticket prices. What will the ticket
price be 10 years after that championship year?

Answer 1

The explicit formula for the ticket price after n years is T(n) = 20 + 4n. Plugging in 10 for n, we find that the price 10 years after the championship will be $60.

Step-by-step explanation:

The question asks us to create an explicit formula to model the increasing price of football tickets after the local team won a championship. If tickets were originally $20 and the price increases by $4 each year, we can use the formula T(n) = 20 + 4n to represent the price of football tickets after n years.

For 10 years after the championship year, we plug 10 into our equation for n: T(10) = 20 + (4 \times 10) = 20 + 40 = $60. Thus, the ticket price will be $60, 10 years after the championship year.

Answer 2

60$

Step-by-step explanation:

if 4$ is per year 20 ÷4 is 5, 5 years have passed and if 10 uears after the champion ship it will be 60 because 4 × 10 is 40 plus the 5 years since it was 20 therefore 20+40 =60
