Suppose a company needs temporary passwords for the trial of a new payroll software. Each password will have two digits followed
by two letters. The letters J, K, and L and the digits 3 and 6 will not be used. So, there are 23 letters and 8 digits that will be used. Assume that the letters and digits can be repeated. How many passwords can be created using this format?
t = time out + time back 11 = d/523 + d/415 find common deneminator 11 = (415d + 523d)/(523*415) 11*523*415 = 415d + 523d 2387495 = 938d d = 2545 miles
