the performing arts department put in its spring show on Friday and Saturday nights. the price of a ticket was the same both nig
Galina-37 [17]
Let p= the price of a ticket
Let c= the cost to put on the show

Formula:
(profit) = (ticket price) * (number of people) - (cost to put on show)
We have two equations here:
500=120p-c
400=100p-c
Solve:
100=20p
⇒p=5
⇒400=100(5)-c
⇒400=500-c
⇒c=100

So the price of a ticket is $5, and the cost to put on the show is $100.

The sum of three numbers is 3068.Two of the numbers are 1266 and 1755,find the third number<br><br>​
ratelena [41]

Answer:

The third number is 47.

Step-by-step explanation:

The sum of three numbers is 3068 - this can be expressed mathematically as:

\displaystyle{x + y + z = 3068}

Given that two of the numbers are 1266 and 1755 (in order) then substitute x = 1266 and y = 1755:

\displaystyle{1266 + 1755 + z = 3068}

Find the third number - solve for z-variable:

\displaystyle{3021 + z = 3068}\\\\\displaystyle{z = 3068-3021}\\\\\displaystyle{z = 47}

Therefore, the third number is 47.
