The formula for the variance is:
Where:

Replacing the mean and the summatory of X:
-15 because there is ten before 25
Answer:
$43.75
Step-by-step explanation:
To find how much the game would have been 20% off from 43.75, you would have needed the expression
43.75*0.8
So to go from 35 to 43.75, you need the expression
35/0.8.
This expression in simpler terms means What is 38, 80% of?
That is how we get 43.75.
35/0.8 = 43.75.
Let's solve your equation step-by-step.
6.75+38x=1314
Step 1: Simplify both sides of the equation.
38x+6.75=534
Step 2: Subtract 6.75 from both sides.
38x+6.75−6.75=534−6.75
38x=132
Step 3: Multiply both sides by 8/3.
(83)*(38x)=(83)*(132)
x=523
Answer:
x=1713
