At a high school championship game 1200 tickets were sold. Student tickets cost $1.50 each and adult tickets cost $5.00 each. Th
max2010maxim [7]

Answer:

Students= 800

Adults= 400

Step-by-step explanation:

Given data

number of tickets= 1200

let students be x

and adults be y

x+y= 1200--------------------1

'

The total revenue collected for the game was $3200

so

1.5x+5y=3200-------------2

Solve 1 and 2 for x and y

x= 1200-y

put this is 2

1.5( 1200-y)+5y=3200-------------2

1800-1.5y+5y= 3200

3.5y= 3200-1800

3.5y=1400

Divide both sides by 3.5

y= 1400/3.5

y=400

Put y= 400 in 1

x+400= 1200

x= 1200-400

x=800

sergeinik [125]

A function assigns the values. The number of people that were recruited in year 6 is 192.

<h3>What is a Function?</h3>

A function assigns the value of each element of one set to the other specific element of another set.

Given that the number of people per year is represented by the function f(t)=3(2)^t.

In the given function, t represents the number of years.

Now, the number of people that were recruited in year 6 can be calculated by putting the value of t as 6 in the given function,

f(t)=3(2)^t

f(6) = 3(2)⁶

     = 3(64)

     = 192

Hence, the number of people that were recruited in year 6 is 192.
