Answer:
The expression for the total amount of tickets sales can be give in dollars as :
⇒ [tex]130y+73,500[/tex]
Step-by-step explanation:
Given:
Cost of a ticket in standing arena = $210
Cost of a ticket for a seat = $130
Total people that can accommodate in standing arena = 350
Total number of seats in the concert = [tex]y[/tex]
To write the expression for the total amount of tickets sales if the concert is sold out.
Solution:
The concert is sold out. This means 350 tickets for standing arena and [tex]y[/tex] tickets for seats are sol out.
Using unitary method to find the total cost.
If a ticket in front stage arena costs = $210
Then, 350 such tickets will cost = [tex]350\times \$ 210=\$ 73,500[/tex]
If a ticket for a seat costs = $130
Then, y such tickets will cost = [tex]y\times \$ 130=\$ 130y[/tex]
Total amount of ticket sales can be given as:
[tex]\textrm{Total cost of seat tickets in dollars sold + Total cost of front stage tickets in dollars sold}[/tex]
⇒ [tex]130y+73,500[/tex]
