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.Use model 1 to determine in which year the cost will be $47,901 for what cost $10,000 in 1975.
