Answer:
<u>x = Number of tickets for the concert</u>
<u>y = Price of the order of x tickets</u>
<u>y = 14.5x + 5</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Order of 4 tickets has a price of $63
Order of 6 tickets has a price of $92
2. Write an equation to find the price of any amount of tickets.
Let's find out the price of a ticket to understand if there's a service fee and how much is it, this way:
Price of a ticket = (Order of 6 tickets - Order of 4 tickets)/2
Price of a ticket = (92 - 63)/2
Price of a ticket = 29/2 = 14.50
If a ticket costs $ 14.50, 4 tickets will cost $ 58 and 6 tickets will cost $ 87, therefore there is a service or delivery fee of $ 5.
Order of 4 tickets - Price of 4 tickets = Service or delivery fee
Replacing, we have:
63 - 58 = 5
Order of 6 tickets - Price of 6 tickets = Service or delivery fee
Replacing, we have:
92 - 87 = 5
Now, we can write the equation to find the price of an order of any amount of tickets, this way:
<u>x = Number of tickets for the concert</u>
<u>y = Price of the order of x tickets</u>
<u>y = 14.5x + 5</u>
