1.
The line graph shows the cost of inflation in some country. What cost $10,000 in 1975 would cost the amount shown by the graph in subsequent The Cost of Inflation years. Below are two mathematical models for the data shown in the graph. In each formula, C represents the cost x years after 1980 of what 40 cost $10,000 in 1975. Answer parts a through c. Model 1 C =882x + 15,095 307 Model 2 C= - 2x" + 945x + 14,030 Cost (thousands of dollars) 20- 10 Year 1980 1990 2000 a. Use the graph to estimate the cost in 2000, to the nearest thousand dollars, of what cost $10,000 in 1975. $ 33,000 (Round to the nearest thousand dollar as needed.) b. Use model 1 to determine the cost in 2000 of what cost $10,000 in 1975. (Round to the nearest dollar as needed.)A new car worth $27,000 is depreciating in value by $3000 per year. Complete parts (a) through (c). a. Write a formula that models the car's value, y, in dollars, after x years. b. Use the formula from part (a) to determine after how many years the car's value will be $18,000. c. Graph the formula from part (a) in the first quadrant of a rectangular coordinate system. Then, show your solution to part (b) on the graph. a. A formula that models the car's value, y, in dollars, after x years isFor a long-distance person-to-person telephone call, a telephone company charges $0.44 for the first minute, $0.26 for each additional minute, and a $2.77 service charge.
