The art museum had a total of 224 visitors on tuesday. visitors older than 18 paid 12 dollars for admission. visitors 18 or younger paid 8 dollars for admission. the museum collected a total of 2,520 dollars. how many visitors were 18 or younger?

The number of visitor 18 years or younger than 18 years is 42 .

Step-by-step explanation:

Given as :

The total number visitor in the museum = 224

The price of admission for visitor older than 18 years = $ 12

The price of admission for visitor 18 years or younger than 18 years  = $ 8

The total price of tickets = $ 2,520

Let The number of  visitor older than 18 years = x

And The number of visitor 18 years or younger than 18 years = y

Now, According to question

The total number visitor in the museum = 224

Or, The number of  visitor older than 18 years  +  The number of visitor 18 years or younger than 18 years = 224

Or, x + y = 224

And $ 12 x + $ 8 y = $ 2,520         ..........A

Or, $ 12 × ( x + y ) =  $ 12 × 224

Or,   $ 12 x + $ 12 y = $ 2688         ..........B

Solving Eq A and B

Or, (  $ 12 x + $ 12 y ) - (  $ 12 x + $ 8 y ) = $ 2688 - $ 2520

Or, (  $ 12 x - $ 12 x ) + (  $ 12 y - $ 8 y ) = $ 168

Or, 0 + 4 y = 168

∴  y =

I.e y = 42

So, The number of visitor 18 years or younger than 18 years = y = 42

And ∵  x + y = 224

I,e  x = 224 - y

or,  x = 224 - 42

∴  x = 182

So, The number of  visitor older than 18 years = x = 182

Hence The number of visitor 18 years or younger than 18 years is 42 . Answer

the nearest power is 1.651.

means 7482 to the 1.651th power is almost equal to 2489287
