1) mode > median > mean

Mean is the average of all data.
22 + 14 + 19 + 22 + 8 + 17 = 102 ÷ 6 = 17
Median is the middle value of the data arranged from lowest to highest:
8, 14, 17, 19, 22, 22 => 17 + 19 = 36 ÷ 2 = 18
Mode is the number that is repeated more often than any other number.
8, 14, 17, 19, 22, 22 => 22

22 > 18 > 17 ==>>> mode > media > mean

The price of one bag of popcorn is $3.75

Step-by-step explanation:

Let,

x represent the cost of a bag of popcorn

y represent the cost of a drink.

According to given statement;

4x+12y=30 Eqn 1

x+6y=11.25 Eqn 2

Multplying Eqn 2 by 2

$2(x+6y=11.25)\\2x+12y=22.50\ \ \ Eqn\ 3$

Subtracting Eqn 3 from Eqn 1

$(4x+12y)-(2x+12y)=30-22.50\\4x+12y-2x-12y=7.50\\2x=7.50$

Dividing both sides by 2

$\frac{2x}{2}=\frac{7.50}{2}\\x=3.75$

4x+12y=30 and x+6y=11.25 can be used to find the price of one bag of popcorn and the price of one drink.

The price of one bag of popcorn is $3.75
