Answer: $13.00
Because it states in the question: Package A charges $15.00 for the first car wash and a dollar less for each car wash after. If they were to wash two cars then a third, the first car would be $15.00 while the second would be $14.00 and the third would be $13.00 since package A is subtracting a dollar every wash.
Answer:
The demand will drop approximately 23 T-shirt per month.
Step-by-step explanation:
Consider the provided formula.

You currently sell T-shirts for $15 each and you raise your price by $2 per month,
That means p=$15 and 
We need to find how fast demand will drop.

Substitute the respective values as shown:


Hence, the demand will drop approximately 23 T-shirt per month.
Answer:
4 ; 32
Step-by-step explanation:
Given that :
Number of observations, n = 9
Let observations = X
ΣX = 360
The mean, (m) is calculated using the formula :
m = ΣX / n
m = 360 / 9
m = 4
Σ(X - m) = 288 (sum of square of deviation )
Variance is calculated using the formula :
[Σ(X - m) / n]
Variance = Sqrt(288 / 9)
Variance = 32
