Later, the teaching assistant in Megan's physics course gives her some advice. "Based on past experience," the teaching assistant says, "working on 70 problems raises a student's exam score by about the same amount as reading the textbook for 1 hour." For simplicity, assume students always cover the same number of pages during each hour they spend reading.
