X = number of tickets sold in advance, and thus cheaper.

x + 206 = number of tickets sold at the door.

now, the ones sold at the door, are more expensive and is more than the early sold tickets, as you know is x + 206.

now, if the early ones cost each one 6 bucks, then the cost for all of them is 6*x, or 6x.

the ones sold at the door are 10 bucks each, and therefore their total cost is 10(x + 206).

now, we know sales in total for both was 6828, therefore,

and surely you'd know what that is.

how many were sold at the door? well, x + 206.

**Answer:**

9 days.

hope it helps

**Step-by-step explanation:**

As per given data

1/x=1/(x+27)+1/(x+3)

1/x=(x+3+x+27)/(x+27)(x+3)

X^2+30x+81=2x^2+30x

X^2=81

X=9

so A&B can together do the work in **9 days**

G(x)=x²

The graph has moved to the right 4 units, therefore the new graph will be:

H(x)=(x-4)²

It has also move 4 units up, therefore the new graph will be:

F(x)=(x-4)²+4

**Answer: **

**F(x)=(x-4)²+4**
