Using Social Security Administration data for selected years from 2012 and projected to 2050, the U.S. consumer price index (CPI) can be described by the equation C = 0.068  + 1.8t + 96 where t is the number of years past 2010. With 2012 as the reference year, a year in which the CPI = 120.56 means goods and services that cost $100.00 in 2012 are expected to cost $120.56 in that year. Find the year in which the CPI is predicted to reach 150.00.

A principal amount of $6,000 is placed in a savings account with 6% annual interest compounded quarterly. Part A: List the total account balances for years 0 through 4. Show all necessary work. Part B: Which type of function best models the data? Part C: Solve for the APY. Show all necessary work.

The average annual cost (tuition, fees, and room and board) at four-year private universities rose from $6,566 in 1980 to $29,188 in 2004. Calculate the percentage rise in cost from 1980 to 2004, and compare it to the overall rate of inflation as measured by the Consumer Price Index. The Consumer Price Index for 1980 is 85.4 and the Consumer Price index for 2004 is 188.6. The percentage rise in cost from 1980 to 2004 is %. (Round to the nearest tenth as needed.) C
