Oregon's public universities will raise tuition by an average of 24 percent over two years if they are forced to take a 30 percent cut in state funding, according to a plan submitted to legislators Monday. University officials say it's a worst-case scenario; the cuts are likely to be closer to 20 percent. But they say a 30 percent cut would result in layoffs, pay cuts and could lose up to 10,000 students in the 86,500-student system.
