Suppose uncle floyd gave you $50 when you were
born and then increased each successive birthday
present by $5. (on your 1st birthday you would
receive $55.)
write an algebraic expression that represents how
much money you receive at each birthday.

1- 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.2- 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 the first question?
