Multiply N on both sides
X = P*N
Answer:
3500
Step-by-step explanation:
The first show attendance was 3000 -2580 = 420 short of the desired average.
The second show attendance was 3000 -2920 = 80 short of the desired average.
In order for the average to be 3000, the attendance at the third show must exceed the desired average by an amount that makes up for the shortfall:
420 +80 = 500
Attendance at the 3rd show must be 3000 +500 = 3500.
_____
<em>Alternate solution</em>
You can also attack this problem in the conventional way: use a variable (x) for the required attendance and write the equation of the average.
(2580 +2920 +x)/3 = 3000 . . . . . . the average is the sum divided by 3
5500 +x = 9000 . . . . . . . . . . . . . . . multiply by 3
x = 3500 . . . . . . . . . . . . . . . . . . . . . . subtract 5500
3500 must attend the third show to bring the average up to 3000.
Good Evening.
We have the following:
10 drops → 0.1 fl oz
1000 drops → V
We multiply in cross:
10V = 1000 * 0.1
10V = 100
V = 100 / 10
V = 10 fl oz.
150 lower level
200 upper level
Let x = lower level and y = upper level. You can then set up an equation for cost as:
35x + 25y = 10,250
and the equation for total tickets as:
x + y = 350.
Solve using any method.
