The only restraints on profit result from the restriction on the domain which in turn place a restriction on profit.  

0≤k. Knives sold cannot be negative.

So the range of profit or p is:

p=[-500, +oo)

Profit increases as the number of knives sold increases.  $200 more profit is gained by each sale of a knife.

4000=200k-500

4500=200k

k=22.5

Since k is for knives sold, it must be an integer value, so a $4000 profit is not possible.  At 22, p=3900 and at 23, p=4100

A 30-gram sample of bacteria has some unknown disease that is killing the bacteria. The amount of bacteria is measured each day
Firdavs [7]
For this case we have an equation of the form:
 y = A * (b) ^ t
 Where,
 A: initial amount
 b: decrease factor
 t: time
 Substituting values:
 y = 30 * (b) ^ t
 To calculate t we use a point in the table.
 We have:
 (t, y) = (1, 28.5)
 Substituting:
 28.5 = 30 * (b) ^ 1
 b = 28.5 / 30
 b = 0.95
 Answer:
 
a. Decay factor is 0.95

FrozenT [24]

Answer:

The correct answer is actually around 21%. Are you sure the question wasn't asking what the approximate percent decrease from 85 to 70 was? Because in that case it would be around 17%.
