The equation is y=x+1
Here's an explanation:
The equation starts out with y since that's what we're told to do. Since the even costs $1, then the total cost would be the total number of attendees +1. The variable for attendees is x, and since the additional cost is $1 per attendee, you don't have to multiply x with anything. So, the answer would be y=x+1. (Everything's in dollars)
It depends on what happens to the price of the item during the sale which is not stated in your problem. So if it cost 6 dollars and goes on sale it should be 6 dollars.
For number 1 I think it is 1.02n because I added the like terms together
For the first one, we will have to factor out the numbers. So 2 times 4x is 8x and 2 times 5 is 10. Our new expression will now be 8x + 10 = 8x + 10. Now, since these are equal, x must equal 1.
