A 6,000-seat theater has tickets for sale at $28 and $40. How many tickets should be sold at each price for a sellout perform

RUDIKE [14]

Answer:

2,100 $28 tickets were sold, and 3,900 $40 tickets were sold!

Step-by-step explanation:

So, we need to write two equations in order to solve this:

We will think of 28 dollar tickets as x, 40 dollar tickets as y.

Now lets make those equations:

$x + y = 6,000$

and

$28x+40y = 193,200$

Now, to solve for x and y, lets set a value for x or y. In this case I will set the value of y:

I will do this by taking $x + y = 6,000$ , and subtracting x to the other side, to get y alone:

$y = 6,000 - x$

Now lets plug in y to our second equation:

$28x + 40(6,000-x) = 193,2000$

$28x+240,000-40x = 193,200$

Now combining like terms and solving for x we get:

$-12x + 240,000 = 193,200$

$-12x = -46,800$

$x=3,900$

Now that we know x, lets solve for y by plugging into our first equation!

$3,900 + y = 6,000$

$y = 2,100$

So now we know that our answer is:

2,100 $28 tickets were sold, and 3,900 $40 tickets were sold!

Hope this helps! :3
