1. A small business buys a computer for $4600. After 4 years the value of the computer is expected to be $200. For accounting purposes the business uses linear depreciation to assess the value of the computer at a given time. This means that if V is the value of the computer at time t, then a linear equation is used to relate V and t.(a) Find a linear equation that relates V and t. Find the depreciated value of the computer 3 years from the date of purchase.2.The monthly cost of driving a car depends on the number of miles driven. Lynn found that in May her driving cost was $310 for 500 mi and in June her cost was $410 for 700 mi. Assume that there is a linear relationship between the monthly cost C of driving a car and the distance driven d.(a) Find a linear equation that relates C and d. (b) Use part (a) to predict the cost of driving 1700 mi per month.3.The manager of a furniture factory finds that it costs $2200 to manufacture 100 chairs in one day and $4600 to produce 300 chairs in one day.(a) Assuming that the relationship between cost C and the number of chairs produced x is linear, find an equation that expresses this relationship.(b) What is the slope of the line in part (a), and what does it represent?There is no slope.The slope is 12, and it represents the cost of producing each additional chair. The slope is 1000, and it represents the cost of producing each additional chair.The slope is 12, and it represents the fixed daily costs of operating the factory.The slope is 1000, and it represents the fixed daily costs of operating the factory.(c) What is the y-intercept of this line, and what does it represent?The y-intercept is 12, and it represents the fixed daily costs of operating the factory.The y-intercept is 1000, and it represents the fixed daily costs of operating the factory. There is no y-intercept.The y-intercept is 1000, and it represents the cost of producing each additional chair.The y-intercept is 12, and it represents the cost of producing each additional chair.
