Answer all parts (a)-(g) of this question.Mette has started Mersea Oysters. She aims to export oysters to Germany where she acts as aprice taker. After a couple of nights of calculations she believes that her cost function is givenby C(q) = 100 + 6q + 2q2, where q denotes kilos of oysters harvested. The market price shewill face in Germany is 50 per kilo.(a) [4 marks] Derive Mette’s marginal cost function.(b) [7 marks] Use your result from (a) to determine the profit-maximizing output level.(c) [7 marks] Explain in words why the supply function for a price taker is the same as themarginal cost function.(d) [8 marks] Calculate Mette’s profit. Illustrate marginal cost and profit in a diagram.(e) [8 marks] Now instead assume that the price is 22. Should Mette produce at this price?(f) [8 marks] Assume again that the price is 22 but that the fixed cost of producing (100) issunk and was taken in the previous period. Should Mette produce at this price in this case?(g) [8 marks] Assume again…

Problem statement A construction company is planning their projects for the year 2023. The company is considering the construction of 20 buildings, each is 3,000 m². In 2018, they have built 8 similar buildings but with smaller areas, and the material costs associated with those 8 buildings are shown in the following table: Building #Area (m²) Cost (S) 1 2 3 4 5 6 7 8 1,430 350,350 1,475 358,326 1,655 385,922 1,790 399,387 1,961 419,004 2,015 427,696 2,375 456,126 2,533 461,765 The materials cost index values are as shown in the following table: Year Cost index 2017 321 2018 332 2019 348 2020 368 2021 379 2022 398 2023 406 In 2019, the company began constructing larger units (3,000 m² units compared to those in 2018 as shown in the first table). The labor hours required to complete the first 3,000 m² unit was 24,000 hours but the labor hours decreased exponentially with time due to the experience gained by workers at a 90% learning slope until reaching the 15th unit, after which a…
A company has established that the relationship between the sales price for one of its products and the quantity sold per month is approximately p = 77 – 0.12D units. The fixed cost is $800 per month and the variable cost $25 per unit produced. What number of units, D*,should be produced per month and sold to maximize the profit per month related to the product? Round your answer to 2 decimal places.
Given problem: The ore of a gold mine in the Mountain Province contains, on average, 0.5 grams of gold per ton. One method of processing costs $1,650 per ton and recovers 93% of the gold, while another method costs only $1,500 per ton and recovers 81% of the gold. If gold can be sold at $8,500 per gram, which method is better, and by how much? Consider the income and cost per ton of ore. Solve for the net receipt of each method. *Round off answer in 2 decimal places. Thank you
3. A civil engineer has invented a walling material that sells for P1,500/unit. The Fixed Cost of his company is P210,000.00 while the variable cost is P800.00/unit. a) What is the average number of units to be sold for the engineer to break even? Also show a graph. b) If the Variable Cost and Fixed Cost are decreased by 10% and 20% respectively, how much is the "NEW BREAK EVEN" in terms of PESOS?
