A firm will break even (no profit and no loss) as long as revenue just equals cost. The value of x (the number of items
Mamont248 [21]

Step-by-step explanation:

(a)

the cost function is

C(x) = 300 + 20x

(b)

the revenue function is

R(x) = 35x

(e)

the profit function

P(x) = R(x) - C(x) = 35x - 300 - 20x = 15x - 300

(d)

break-even is the point where C(x) and R(x) are equal :

C(x) = R(x)

300 + 20x = 35x

300 = 15x

x = 300/15 = 20

so, the break-even is only achieved when 20 units are produced and sold. and with more than 20 sold units the business would then make a profit.

per our restrictions only max. 19 units can be sold, so, the business will always be in the negative numbers (unless they cheat and sell virtual units that were never produced).

therefore, the product should not be produced at all.

Based on the graph below, what is the solution of the equation f(x) = g(x)? graph of function f of x equals negative x plus 0.25
nasty-shy [4]
Hello :
f(x) = -x+0.25
g(x) = x²+3x+2
ــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ
f(-3.5) = 3.75

g(-3.5) = 3.75


ـــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ
f(-0.5) =0.75
g(-0.5) = 0.75
ــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ
conclusion : answer : <span>A) x = −3.5 and x = −0.5 </span>

The margin of error can be calculated with the formula:

ME = z · √(p(1-p)/n)

where:
p = sample proportion
n = sample size
z = z-score

In your case:
p = 90 / 120 = 0.75

ME = 2.58 · √(0.75·0.25/120)
      = 0.10
      = 10%

The margin of error will be 10%.
