I would try going with 12.2
Step-by-step explanation:
If I'm correct this is very simple.
x=15
So plug that into the equation and you get
11.00+0.08x15
which equals 12.2

Discount, as you are lowering the item price from 100% (Default ) to 75%
Discount = 100% - 75% = 25%
If it was required to find the discount.
discount = 0.25 x Price.
newPrice = 0.75 x Price
Original price = Discount + new Price.

Y=kx where k is the constant proportionality
y=kx
(1)=k(2)
1/2=k2/2
1/2=k
We can solve this problem by using the formula:
s = σ / sqrt(n)
where,
s = standard deviation of the sample
σ = standard deviation of the population = 3 years
n = number of samples = 100
Substituting:
s = 3 years / sqrt (100)
s = 0.3 years (ANSWER)
