Use the Consumer Price Index below to answer the question.
Between 1990 and 2000, a college raised its annual tuition fees from $4490 to $6650. Find the relative change in the fees over that period and compare it to the overall rate of inflation as measured by the CPI. Were the tuition increases in line with inflation? If necessary, round values to the nearest tenth.
