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,

\bf \stackrel{in~advance}{6x}~~+\stackrel{at~the~door}{10(x+206)}=6828\implies 6x+10x+2060=6828
\\\\\\
16x=4768\implies x=\cfrac{4768}{16}

and surely you'd know what that is.

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

Answer:

1.00434

Step-by-step explanation:

Given the following :

Given a normal distribution ;

Mean (m) = 1.0 liter

Standard deviation (σ) = 0.01 liter

Sample size (n) = 25

For 97% sample means (sm) = 0.97

Z = (m - sm) / s

Zcrit = 1 - (100% - 97%)/2

Zcrit = 1 - (0.03/2)

Zcrit = 1 - 0.015 = 0.985

The z score which corresponds to 0.985 = 2.17

Upper limit : m + z*(σ/√n)

Upper limit : 1.0 + 2.17*(0.01/√25)

Upper limit : 1. 0 + 2.17*(0.01/5)

= 1.0 + 2.17*0.002

= 1.0 + 0.00434

= 1.00434
