| Example 3 |
Sally is planning her birthday party. She wants to watch the new Jim Banter secret agent movie with 20 of her closest friends and family members. Tickets cost $9.00 each. Express the total cost, \(T \), as a function of the number of tickets purchased, \(n \), and then determine how much Sally needs to spend in total for all 21 tickets.
Function: \(T(n) = 9n \)
\(T(n) = 9n \)
\(n = 21 \) tickets
\(T(21) = 9(21) \)
\(T(21) = 189 \)
Sally will need to spend $189.00 for 21 tickets to the movie.
\(T(n) = 9n \)
\(n = 21 \) tickets
\(T(21) = 9(21) \)
\(T(21) = 189 \)
Sally will need to spend $189.00 for 21 tickets to the movie.
