Andrei [34K]

Answer:

A function that gives the of tickets is given by

t(w)=200(1.1)^u

where u is number of consecutive wins

Step-by-step explanation:

Given that,

Initial amount of fans is =200.

For each wins, the number ticket sells is also increased by a factor of 1.1.

After 1^{st} win, the number of tickets fans will be 200×1.1

After 2^{nd} win, the number of tickets fans will be 200×1.1×1.1

                                                                              =200(1.1)²

After 3^{rd} win, the number of tickets fans will be 200×1.1×1.1×1.1

                                                                             =200(1.1)³

and so on.

After u^{th} win, the number of tickets fans will be 200(1.1)^u.

A function that gives the of tickets is given by

t(w)=200(1.1)^u

where u is number of consecutive wins
