When you are building a new home it is important to have an idea from the very start how much it may cost. The price varies dramatically depending on the size and the design of the property. Your task is to analyse the data from past construction works in order to estimate the contribution of different components. The table below show a part of construction costs breakdown (in thousand dollars) for three houses: the first has four bedrooms and three bathrooms, the second has two bedrooms and two bathrooms, and the third has two bedrooms and one bathroom. House 4beds & 3baths 2beds & 2baths 2beds & 1baths Plumbing 14 11 8 Electricity 15 10 9 Flooring 10 7 6 (a) Find real constants Phed, Pbath, Po such that P(x, y) = Pbed ⋅ x + Pbath · y + Po equals the plumbing costs given in the table, where x is the number of bedrooms and y is the number of bathrooms. Similarly, find functions E(x, y) = ebed x + €bath · Y + Co and F(x, y) = ƒbed ·x + ƒbath · y + fo describing the costs for electricity and flooring, respectively.

Help me please, this is confusing.

A group of sales reps receive bonuses if they exceed theier monthly quotas for unit sales.  Over a particular six-month period, their monthly comparisons to their quotas were:  -24, -16, +33, +12, -19, and +8 units.  How far above or below the quotas were they for the entire six-month period?

Netflix made headlines in September 2011 when it split its streaming video service and its DVD by-mail service into two companies. This decision was based on projections that streaming videos will replace DVDs in the future. In this problem, you will explore these projections. Numbers below are close to the correct values, but vary to allow more practice with this idea.  Total DVD and Blu-ray disc sales in 2009 were $8.72 billion. For the purposes of this problem, you will combine DVD and Blue-ray disk sales into one category of DVD sales. A study by In-Stat predicted that "physical disc sales will decline by $4.7 billion by 2014," and that "streaming, on the other hand, should grow from its current $2.1 billion to $6.3 billion over the same time period (2009–2014)." What is the slope, including units, of the model for streaming videos?

Suppose that a company needs 1,500,000 items during a year and that preparation for each production run costs $900. Suppose also that it costs $14 to produce each item and $3 per year to store an item. Use the inventory cost model to find the number of items in each production run so that the total costs of production and storage are minimized.

Refer to the production possibilities curves for Chairland and Tableland. Chairland can produce 36 chairs per day and no tables, or 18 tables table per day and no chairs. Tableland can produce 40 chairs per day and no tables, or 40 tables per day and no chairs. If the two countries split the difference between the​ buyer's willingness to pay for tables and the​ seller's willingness to​ accept, in terms of the number of chairs for 1​ table, the terms of trade will be . (Enter your response rounded to one decimal​ place.) Country  Quantity per day Opportunity cost of chairs  Opportuity cost of tables Tableland 40 chairs, 40 tables 1 table 1 chair Chairland 36 chairs, 18 tables 1/2 table  2 chairs

A retailer anticipates selling 1,300 units of its product at a uniform rate over the next year. Each time the retailer places an order for a units, it is charged a flat fee of $25. Carrying costs are $26 per unit per year. How many times should the retailer reorder each year and what should be the lot size to minimize inventory costs? What is the minimum inventory cost? They should order units The minimum inventory cost is $ times a year.

The new city water company that you have researched charges homeowners based on how much water they use in thousands of gallons. The company progressively charges at a higher rate the more water that is used. Cost of Water Bill (dollars) 240 230 220 210 190 180 170 160 110 Water Usage (in thousands of gallons) 11. Based on the graph above, how much does the city charge when a homeowner uses the following number of gallons of water: a) 1700 gallons of water b) 2000 gallons of water c) 7000 gallons of water 12. Finish filling in the following piece-wise equation below that describes the chart based on the graph 50 if 0 < x <2 5x+50 y = if 6≤x≤8 30x 140
