- Three athletic clubs offer different membership costs. The first club charges $20 per month. The second club charges $20 per month plus an application fee of
$10. The third club charges $20 per month and offers a $15.00 reduction in the
first month's membership fees. Write the equations that model the total cost of
membership at the three clubs. Describe how the second and third graphs are
related to the graph of the first club.

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?
