Jose goes to the bodega. He buys a soda for $1.50 plus 2
bags of chips.
He spends a total
of $4. How much does 1 bag of
chips cost?

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?
