A machine costs P 8,000.00 and an estimated life of 10 years with a salvage value of P500.00. What is its book value after 8 years using straight-line method?
An fruit grower knows from previous experience and careful data analysis that if the fruit on a specific kind of tree is harvested at this time of year, each tree will yield, on average, 130 pounds, and will sell for $0.6 per pound. However, for each additional week the harvest is delayed (up to a point), the yield per tree will increase by 7 pounds, while the price per pound will decrease by $0.02.A) How many weeks should the grower wait before harvesting the apples in order to maximize the sales revenue per tree? (Round your answer to the nearest tenth of a week.)Answer: (rounded to the nearest tenth)B) Use your answer in part A to find the actual maximum revenue that can be expected. (Round your answer to the nearest dollar.)Answer: dollars (rounded to the nearest dollar)
If it's possible could I get the percentage rounded to two decimal places please

- How do I prove my estimate?arrow_forwardWe found that the estimated rate of increase in the cost when x = 60,000 is $438 per game system. We are asked to compare this estimate to the exact cost of producing the 60,001st game system. In order to find the exact cost of producing the 60,001st game system, we can find the exact cost of producing 60,000 game systems in an hour and the exact cost of producing 60,001 game systems in an hour and take the difference of the two numbers. Recall that the cost for the company to produce x game systems per hour is given by the cost function C(x) = 900,000 + 390x + 0.0004x2. So the cost for the company to produce 60,000 game systems in an hour is given by the following. C(x) = 900,000 + 390x + 0.0004x2 C(60,000) = 900,000 + 390(60,000) + 0.0004(60,000)2 = 25740000 The cost for the company to produce 60,001 game systems in an hour is given by the following. C(x) = 900,000 + 390x + 0.0004x2 C(60,001) = 900,000 + 390(60,001) +…arrow_forwardA typical treatment for Acinetobacter baumannii infection, for example, is a regimen of ampicillin, consisting of 250 mg, 4 times a day for 1 week.
