1. In problems a and b, cost functions are given, where c is the cost of producing and q units of a product. In each case, find the marginal cost function. What is the marginal cost at the given values of q? a. c = 500 + 10q²q = 100
The marginal cost function is the derivative of the cost function with respect to the quantity of the product being produced. To find the marginal cost function, we must first find the derivative of the cost function.
In this case, the cost function is:
c = 500 + 10q²
To find the derivative, we use the power rule, which states that the derivative of a function of the form f(x) = x^n is n * x^(n-1). In this case, we have:
dc/dq = 10 * 2 * q^(2-1) = 20q
Therefore, the marginal cost function is:
mc = 20q
To find the marginal cost at a given value of q, we simply plug that value into the marginal cost function. For example, if q = 100, the marginal cost is:
mc = 20 * 100 = 2000.
In summary, the marginal cost function is mc = 20q, and the marginal cost at q = 100 is 2000.
2. The market price of a food processor is $95. It is sold at a loss of 26% on the cost price. Find the cost price of the food processor
Jawaban:
$24.70
Penjelasan dengan langkah-langkah:
100%->$95
1%->95÷100=0.95
26%->0.95×26=_24.7_
=_24.70_
3. In problems a and b, cost functions are given, where c is the cost of producing and q units of a product. In each case, find the marginal cost function. What is the marginal cost at the given values of q? a c= 0.2q² +4q+50 q = 10
Jawaban:
Untuk menemukan fungsi biaya marjinal (marginal cost function) dari suatu fungsi biaya (cost function), kita dapat menggunakan rumus turunan dari fungsi tersebut. Dalam hal ini, kita dapat menggunakan rumus turunan dari fungsi c = 0.2q² + 4q + 50, yaitu c' = 0.4q + 4, sebagai fungsi biaya marjinal. Dengan menggunakan fungsi tersebut, kita dapat menemukan biaya marjinal pada q = 10 dengan mengganti nilai q dengan 10 pada fungsi c':
c'(q) = 0.4q + 4
c'(10) = 0.4 * 10 + 4
= 4 + 4
= 8
Jadi, biaya marjinal pada q = 10 adalah 8.

12. Find the cost of fencing a circle with radius 7cm at rupees 30per m
Jawab:
6.8₹
Penjelasan dengan langkah-langkah:
circumference of cirle = [tex]2\pi r[/tex]
= 2 x 11/7 x 7 cm
= 22/7 x 7
= 22 cm
fencing cost = 30₹ / m
100 cm = 1m
= (22/100) x 30
= (11/50) x 30
= 330/50
= 33/5
= 6 3/5
= 6.8₹
Given:
Radius : 7cmCost of fencing per metre: 30m²ToFind:-
Cost of fencing with radius: 7cmSolutionwithStepbyStepExplanation:-
Circumference of Circle = 2πr
= 2 × 22/7 × 7
= 44cm
1 m = 1000cm =
so, 1000/44 = 0.44m
Hence, The circumference of Circle is 0.44m
Now, we have to find the Cost of Fencing!
Cost of fencing at m² = 30m²
Cost of fencing at 0.44m = ₹13.2
.°. Cost of Fencing at 0.44m is ₹13.2

19. The cost of 6 refrigerators and 5 washing machines is $23 639.The cost of each refrigerator is $1650 more than the cost of a washingmachine. How much does a washing machine cost?
the cost of a washing machine is $1249
x = refrigerator
y = washing machines
6x + 5y = $23639
x = y + $1650
x = ?
6x + 5y = 23639
6(y + 1650) + 5y = 23639
6y + 5y + 9900 = 23639
11y = 23639 - 9900
11y = 13739
y = $1249
x = y + 1650
x = 1249 + 1650
x = $2899
20. 1. Pengorbanan yang dilakukan karena dipilihnya suatu alternatif kebutuhan tertentu diantara berbagai alternatif pilihan, dalam teori ekonomi disebut.... a. the cost of doctrin alternative b. the cost of marketing alternative c. the cost of production alternative d. the opportunity cost e. the cost of choice alternative
Pengorbanan yang dilakukan karena dipilihnya suatu alternatif kebutuhan tertentu di antara berbagai alternatif pilihan disebut = The Opportunity Cost / Biaya Peluang.
Jadi Biaya Peluang itu, semisalkan kita dikasih pilihan buat makan bakso, atau mi ayam. Kalau kita makan bakso, maka biaya peluang / Opportunity Cost kita adalah mi ayam.
Semoga memba :)
