Answer:
1) the purchase price
(4.30+1.45)*2000
5.75*2000
11500€
2) the profit
(1750*10.50+(2000-1750)*8.50)-11500
18375+2125-11500
9000€
Step-by-step explanation:
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
Answer: The leading coefficient is -1.
Step-by-step explanation: Coefficients are the numbers than procede each term with a variable (in this instance,<em> </em>x) in the equation.

There are four terms in this equation, which has been reordered in the correct form, which is from the highest term to the lowest term (based on exponent values).
Thus, there are three coefficients in this equation, which, in order, are as follows:

Answer:
the problem is the comparison with the calculated time for Jillian and the actual time for Jillian to run the 7 miles. Note: 16% error is the approximate error because the numbers have 2 significant figures stated in the problem.
