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
