The line graph shows the cost of inflation in some country. What cost $10,000 in 1975 The Cost of Inflation would cost the amount shown by the graph in subsequent years. Below are two 40 mathematical models for the data shown in the graph. In each formula, C represents O the cost x years after 1980 of what cost $10,000 in 1975. Answer parts a through c. 30 Model 1 C= 875x + 15,330 Cost (thousands of dollars) 20 Model 2 C= - 2x2+ 938x + 14,351 10- Year 1980 1990 2000 Le Lie ue a. Use the graph to estimate the cost in 2000, to the nearest thousand dollars, of what cost $10,000 in 1975. ge ue (Round to the nearest thousand dollar as needed.) Jes
