A movie theater has a seating capacity of 387. The theater charges $5.00 for children, $7.00 for students, and $12.00 of

Rainbow [258]

Answer:

The attendance was 198 children, 90 students and 99 adults.

Step-by-step explanation:

We define:

c: children attendance

s: students attendance

a: adult attendance

The equation that describes the total ticket sales is:

$5c+7s+12a=2808$

We also know that the children attendance doubles the adult attendance:

$c=2a$

The third equation is the seating capacity, which we assume is full:

$c+s+a=387$

We start by replacing variables in two of the equations:

$c=2a\\\\s=387-c-a=387-2a-a=387-3a$

Then, we solve the remaining equation for a:

$5c+7s+12a=2808\\\\5(2a)+7(387-3a)+12a=2808\\\\10a+(2709-21a)+12a=2808\\\\10a+12a-21a=2808-2709\\\\a=99$

Then, we solve for the other two equations:

$c=2a=2*99=198\\\\s=387-3a=387-3*99=387-297=90$

The attendance was 198 children, 90 students and 99 adults.

If the flotation costs are 2 percent of gross proceeds, and gross proceeds are $250,000, what is the dollar amount of flotation

alina1380 [7]

The dollar amount of the flotation costs by percent of gross proceeds is $5,000

We need to know about the percent theory first, percent is per 100. So when A is 1% of B it means that

A = 1/100 x B

From the question, we know that

The gross proceeds is given by = $250,000 and

the flotation cost is given by = 2% of gross proceeds.

We can write the flotation cost as

Flotation cost = 2/100 x $250,000

Flotation cost = 2/100 x $250,000

Flotation cost = $5,000

Hence, the dollar amount of the flotation costs is $5,000
