3. Trevor's weekly allowance is calculated using a point system. For each chore he does, Trevor
gets a point. For each chore he misses, he loses a point. Each point is worth S2, and negative
points mean that Trevor owes money to his parents. If Trevor has a total of 8 assigned chores
each week, how much can he expect to earn or owe using this point system?

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis. 3- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in part b?
