Answer:
B= 15 adults tickets
C= 35 student tickets
Step-by-step explanation:
x+y=50
solve for y
y=50-x
5x+3y=180
5x+3(50-x)=180
5x+150-3x=180
2x=30
x=15
y=50-15
y=35

So here's the solution to the problem:
Calculate the average sell:
1,700 * $25 = $42,500 (revenue)
And if the Opera House wants to increase their revenue:
The price of a ticket will be:
$25 - x (where x is the number of 1-dollar decreases)
The number of tickets in total:
1,700 + 200x
Therefore the equation is:
(1,700 +200x) * ( 25 - x ) = 55,000
We can also solve this equation, but the solutions are not whole numbers.
x 1 = 5.89 and x 2 =10.6
For x = 6 (6 times 1 - dollar decreases):
( 1,700 + 200 * 6 ) * ( 25 - 6 ) = ( 1,700 + 1,200 ) * 18
=2,900 *19 = 55,100 (we will yield the revenue over $55,000)
Answer:
43
Step-by-step explanation:
You will have to use the PEMDAS rule here. so Parntheses goes first, then exponents, then mutiplicaton or division, and finally addition or subtraction.
20-7= 13
-2^2 = (-2 * -2) = 4
9/3 = 3
so... 13*3 = 39+4 =43
