- a- The Western U.S. saw record heat waves in August, 2021. Electricity is heavily used in air conditioning leading to very high demand for electricity then. Would you expect the marginal costs of generating electricity to be similar to in May, 2021, lower orhigher? Why? b- Suppose California could add 1000 MWh of wind generation—which produces for four hours during the nighttime when temperatures are relatively low—or 1000 MWh of solar generation—which produces for four hours in the daytime when temperatures are relatively high. Which one would you have expected to lower total costs of electricity generation more in the summer? Why? Please explain by sketching the daytime and nighttime marginal cost curve for electricity and showing the size of the cost reductions.arrow_forward5. Rusty Trawler imports oil from Saudi Arabia. His cost function (for purchasing and delivering the oil) is TC = 5000+.1Q² where Q is the number of barrels of oil delivered. He may sell all the oil he can deliver for $60 per barrel (so TR = 60Q). Given these conditions, what are Rusty's maximum possible profits? a) $0 b) $300 c) $2,500 d) $4,000arrow_forward1/3 1/3 Assume y = f(x1, x2) = x1 x2 .

- What is the marginal cost forumla for TC= 10+5Q?arrow_forwardGiven that the variable cost is $25 per customer, with a fixed cost of $200, he needs to fnd which price maximizes, therefore my question is how do I find what amount he earns if profit is maximized.arrow_forwardwhat is efficient scale in economicsarrow_forward
- The marginal cost for a company to produce q items is given by MC(q)=0.004q2−0.6q+620. The company's fixed costs are $8500. Find the marginal cost at a production level of 400 items. The marginal cost at a production level of 400 items is ??? per item.arrow_forwardSuppose you make beautiful coffee tables out of juniper trees. Your materials cost for each table is $135. You pay your craftsman $25 per hour and it takes him 5 hours to complete one table. If you sell these tables for $689, what is your Cost of Goods Sold Percentage? 2. What is the Gross Profit Margin on the coffee tables described in question 1 above? 3. Suppose your company sells a 3 pack of lenses that attach to smart phones to improve the quality of pictures people take. You pay $29.95 for each 3 pack and sell them for $59.95. What is your Cost of Goods Sold Percentage for this item? 4. Suppose you sell 8,000 of the 3 pack of lenses described in question 3 above in one year. You cost on each 3 pack is $29.95 and you sell them for $59.95. If your operating expenses for the year total $144,080, what are your Net Income and Net Profit Margin Percentage? 5. Suppose an investor gave you $150,000 to start your business. You gave this investor 50 percent of your company for…arrow_forwardHand written solutions are strictly prohibitedarrow_forward
