Pls Help! Its due today! No links or I will report! Please put a proper answer! David deposited $3,500 in two banks. The first bank paid 2% simple interest per year while the second bank paid 3%. At the end of one year, the difference in the interest amounts was $30. Find the amount David deposited in each bank.

Suppose that 3% of all athletes are using the endurance-enhancing hormone epo (you should be able to simply compute the percentage of all athletes that are not using epo). for our purposes, a “positive” test result is one that indicates presence of epo in an athlete’s bloodstream. the probability of a positive result, given the presence of epo is .99. the probability of a negative result, when epo is not present, is .90. what is the probability that a randomly selected athlete tests positive for epo? 0.0297
