6.9 = 6.9 / 1
Numerator = 6.9 × 10 = 69
Denominator = 1 × 10 = 10
Numerator / Denominator = 69 / 10
Simplifying our fraction
= 69/10
= 69/10
= 6 9/10
part A:
company a
30m+15
m= matress
company b
28m+21
m=matresses sold
part B:
company a
30(6)+15
195$
company b
28(6)+21
189$
company B charges less
part C:
company a
30(3)+15
105$
company b
28(3)+21
105$
there is no change at all so you do not save anything.
Answer:
Step-by-step explanation:
Answer:
x = 4 units
Step-by-step explanation:
Data provided in the question:
c(x ) = 2x³ - 12x² + 23,000
Now,
For point of maxima or minima, differentiating the above equation with respect to number of items 'x'
c'(x) = 3(2x²) - 2(12x) + 0
or
c'(x) = 3(2x²) - 2(12x)
for point of maxima or minima put c'(x) = 0
Thus,
3(2x²) - 2(12x) = 0
or
6x² - 24x = 0
or
x² - 4x = 0
or
x(x - 4) = 0
or
x = 0 and, x = 4
Since,
The quantity cannot be zero
Therefore,
production level that will minimize the average cost of making x items is x = 4 units
