Question

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 sodas at $1.50 each, and 2 candy bars at $1.00 each. To the nearest cent, what is the average (arithmetic mean) amount of these snack sales per ticket sold?

Answer 1

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

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* 3` = $6.75

Number of soda sold = 4

Cost of a soda = $1.50

Total cost of soda =
`1.50* 4` = $6.00

Number of candy bars sold = 2

Cost of a candy bar = $1.00

Total cost of candy bars =
`1.00* 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 =

`\frac{\text{Total sales}}{\text{Number of tickets}} = (14.75)/(10) = 1.475`

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