Answer:
205.92
Step-by-step explanation:
just basic math
We are given with the formula
p = 200k - 500
a) The constraint for this formula is obtained from the idea that the profit must be positive
200k - 500 > 0
k > 500/200
k > 2.5
b) To make 14000 profit
14000 = 200k - 500
k = 72.5 or 73 knives must be sold
Ok, so remember the exponentioal law that says

so

answe ris x^6
6% of 160, 000 = 9600 dollars
