Problem 1. A set I ≤ R is called an interval if for all triples of real numbers x, y, and z such that x < z < y, if x € I and y € I then z € I. Prove that every interval takes exactly one of the following nine forms: (-∞,b), (-∞,b], (a,b), (a,b], [a,b), [a,b], (a, ∞), [a, ∞), or (-∞, ∞). (Hint: You have to consider an arbitrary set I satisfying the condition in the problem and prove something about it. Consider cases according to whether I is (unbounded above / bounded above and contains its sup / bounded above and does not contain its sup), and similarly for below. You should have 3-3 = 9 cases.")
In an orchestra, 23 people can play stringed instruments, 21 can play brass, and 15 can play percussion. Further, 9 of the performers can play both strings and brass, whereas 8 can play both strings and percussion. If no one can play all three types of instruments, what are the maximum and minimum numbers of people in the orchestra? (Hint. Consider expressing the numbers in some of the regions of your diagram in terms of a single unknown, say x.)

3. Jack and Jill work at the same store. Jack's total weekly salary, in dollars, if he sells x items is given by S= = 100 + 5x, and Jill's total weekly salary, in dollars, if she sells x items is given by S = 80 + 6x. If they sell the same number of items in a week, what is the minimum number of items they have to sell so that Jill's weekly salary is at least $300 more than Jack's? Ver
