Urgent *will medal*: Choose a variable to represent the unknown in this problem. Write an equation and solve: Mr. James is looking for the best deal on tickets for the concert. At the box office he would have to pay $15.75 for a ticket. On the Internet he could purchase tickets for 4/5 of that price. How much would 6 tickets cost over the Internet?

Thanks c:

We don't know the cost so we will label that "c"
we want to know how much 6 tickets will cost for 4/5 the price of tickets at 15.75 right?

Yeah...

Hm...would it be written as an inequality?

anonymous · Answer

That could work. 
but i feel like we could make it easier by trying to simplify what we already have

anonymous · Answer

the price of a ticket online is 4/5 that of 15.75
what would be an easier way to write that?

anonymous · Answer

Let the cost of the ticket on the internet be x.

For 1 ticket on the internet,
4/5 ($15.75)
= $12.60.

You need 6 tickets,
Therefore 6 ($12.60)
Answer is $ 75.60

anonymous · Answer

We could say that a ticket online is 4/5 (15.75)= 12.60
We have the price for a ticket online and want to know the total cost of multiple tickets along with c, we could use t for tickets and use the equation
y=ct
we know c which is 12.60
y=12.60t
t=6
y=(12.60)(6)
y=$75.60
