Depreciation Once a new car is driven away from the dealer, it begins to lose value. Each year, a car loses 10% of its value. This means that each year the value of a car is 90% of the previous year’s value. If a new car was purchased for $20,000, the value at the end of the first year would be $20000(0.90) and the value of the car after the end of the second year would be $20000(0.90)2. Complete the table shown below. What will be the value of the car at the end of the eighth year? Simplify the expression, to show the value in dollars.
For the following exercises, consider this scenario: The profit of a company increased steadily over a ten-year span. Thefollowing ordered pairs show the number of units sold in hundreds and the profit in thousands of over the ten-yearspan, (number of units sold, profit) for specific recorded years: (46,250),(48,305),(50,350),(52,390),(54,410). Predict when the profit will exceed one milliondollars.
For the following exercises, consider this scenario: The profit of a company increased steadily over a ten-year span.

Use linear regression to determine a function y,where the profit in thousands of dollars depends onthe number of units sold in hundreds.
The US. import of wine (in hectoliters) for several years is given in Table 5. Determine whether the trend appearslinear. Ifso, and assuming the trend continues, in what year will imports exceed 12,000 hectoliters?
For the following exercises, consider this scenario: The profit of a company decreased steadily over a ten-year span.The following ordered pairs show dollars and the number of units sold in hundreds and the profit in thousands ofover the ten-year span (number of units sold, profit) for specific recorded years: (46,250),(48,305),(50,350),(52,390),(54,410).

For the following exercises, consider this scenario: The median home values in subdivisions Pima Central and East Valley (adjusted for inflation) are shown in Table 1. Assume that the house values are changing linearly. If these trends were to continue, what would be the median home value in Pima Central in 2015?
For the following exercises, consider this scenario: The profit of a company decreased steadily overa ten-year spam.The following ordered pairs shows dollars and the number of units sold in hundreds and the profit in thousands ofover the ten-year span, (number of units sold, profit) for specific recorded years: (46,600),(48,550),(50,505),(52,540),(54,495). Use linear regression to determine a function Pwhere the profit in thousands of dollars depends onthe number of units sold in hundreds.
For the following exercises, use the median home values in Indiana and Alabama (adjusted for inflation) shown in Table 3. Assume that the house values are changing linearly. If we assume the linear trend existed before 1950 and continues after 2.000, the two states median house values will be (or were) equal in what year? (The answer might be absurd.)
