A family rents a large van for vacation. It costs $80 per day plus a $155 insurance
fee. Which equation could be used to
find x, the number of days the car can be
rented if they want to spend exactly $875
on the van rental?

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?
