Each peach costs $0.56 and the equations used to solve that is
where x is the cost of 1 peach.
Step-by-step explanation:
Step 1:
It is given that all the peaches weigh the same and that 4 peaches weigh 1 pound.
Assume that each peach costs x.
So the cost for 4 peaches is given by 
Step 2:
The cost of 1 pound of peaches is given as $2.24.
1 pound of peaches
So 

So each peach costs $0.56.
F(x) = ln(x² - 12x)
The derivative is

f(x) is undefined when x² - 12x = x(x - 12) = 0
That is, when x = 0 or x = 12.
Therefore the domain is (-∞, 0)∪(0,12)∪(12, ∞)
Answer:
The derivative is

The domain is
(-∞, 0)∪(0, 12)∪(12,∞)
40 doubles every 15 hours
40hours / 15hours = 2 and 2/3
2 2/3 x 40 =
106 and 2/3, rounded to 107
Hope this helps
