How much did a year of tuition at a public 4-year college (in-state) cost?
A year of tuition at a public 4-year college (in-state) cost $433 in 1975 and $11,950 in 2025: about 28 times as much.
Over the same years, prices in general (US inflation, measured by the consumer price index, CPI) rose about 6 times. That makes $433 in 1975 worth about $2,590 in 2025 money. So it got more expensive even after inflation: about 361% more, in real terms, than in 1975.
The biggest change between two listed years came between 1975 and 1980, when it went up 86%, from $433 to $804.
