The Cost of Inflation 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 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 cost $10,000 in 1975. Answer parts a through c. 40+ 30- Model 1 C = 931x + 15,188 20- Model 2 C= - 2x + 998x + 14,188 10- Year 0- 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. $ 35,000 > (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.) Cost (thousands of dollars)
