The table below shows outstanding consumer credit (in billions of dollars) at the beginning of various years.  Year Credit 1980 350 1985 524 1990 798 1995 1010 2000 1539 2005 2197 2010 2544 2015 3330 1. Use your calculator to find an exponential model for these data, where t = 0 corresponds to the year 1980. Round values to two decimal places. 2. If this model remains accurate, what will the outstanding consumer credit be in 2030? Round to two decimal places, and include units in your answer. 3. Use your calculator to determine the first full year where consumer credit exceeds $5000 billion.
