Juan loves pizza. Juan knows that the pizza spot he orders from charges $20 for a party size cheese pizza. They also charge $2.50 for each additional topping. This can be modeled with the
rule, y= 2.5x + 20, where x represents the number of toppings and y represents the total cost
of the pizza. If Juan wants 4 toppings on his party size pizza, how much will it cost him?

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?
