Jessica borrowed $1,450 for three months at an annual rate of 8.75% under a single-payment plan. How much interest must she pay?

Please show the work I would like to actually know how to do it. Thanks.

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?
