Step-by-step explanation:

Given:

The drama club sold 2100 tickets to their last play.

Student tickets were $5 and adult tickets were $7.

They collected $12,950.

Now, to find the number of student tickets sold.

Let the number student tickets be

And the number adult tickets be

So, the total number of tickets:

Now, the total amount collected:

Putting the value of from above:

Subtracting both sides by 14700 we get:

Dividing both sides by -2 we get:

The number of student tickets = 875.

Therefore, 875 student tickets were sold.

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
