The angles in a quadrilateral must add up to 360 degrees. So, if we add up the first three sides we get 77 + 180 + 65 = 322 degrees. The last side is going to be 360 - 322 = 38 degrees.

The manager of a theater noted that for every 10 admission tickets sold, the theater sells 3 bags of popcorn at $2.25 each, 4 so

Shalnov [3]

Answer:

$1.475 is the average amount of snack sales per ticket sold.

Step-by-step explanation:

We are given the following in the question:

Number of popcorn bags sold = 3

Cost of a popcorn bag = $2.25

Total cost of popcorn bag = $2.25\times 3$ = $6.75

Number of soda sold = 4

Cost of a soda = $1.50

Total cost of soda = $1.50\times 4$ = $6.00

Number of candy bars sold = 2

Cost of a candy bar = $1.00

Total cost of candy bars = $1.00\times 2$ = $2.00

Total sales =

Total cost of popcorn + Total cost of soda + Total cost of candy bar

$= 6.75 + 6 + 2\\=\$14.75$

$\text{Average} = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}$

Average amount of snack sales per ticket sold =

$\dfrac{\text{Total sales}}{\text{Number of tickets}} = \dfrac{14.75}{10} = 1.475$

Thus, $1.475 is the average amount of snack sales per ticket sold.
