Short Answer

Expert verified

The girls who paid are 9 and the adults are 3

Step by step solution

Step 1.Given information

We have been given

Amount each girl paid = $75.

Each adult paid = $30.

Total amount = $765.

Let the number of adults be $x$ .

The girls tickets three times of the adults ticket .

The girls ticket is $3 x$ .

step 2.Additional information

Tabulate the information

Type	Number	Value($)	total value($)
Adults	$x$	30	$30 x$
girls	$3 x$	75	$75 (3 x)$

the total amount collected is 765$.

step 3. Forming equation

Since the total values is $765 $$ .

$30 x + 75 (3 x) = 765$

step 4.Sloving the equation

$30 x + 225 x = 765 255 x = 765 x = \frac{765}{255} x = 3$

step 5.The solution

The adults are $x = 3$ .
The girls are $3 x = 3 (3) = 9$ .
