An electronics company is planning to introduce a new line of computers. for the 1st year, the fixed costs for setting up the production line are $200,000. the variable costs for producing each computer are $40. the revenue from each computer is $65. find the total profit p(x) from the production and sale of x computers and break-even point.

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?
