a movie theather was opened in a small town. every customer whose ticket number has at least three same digits has a 15 percent discount. how many costumers with ticket number 1001 to 1500 recieve the discount
I'm not sure if this is correct but the answer would be 4. Since the only numbers with at least 3 of the same digits are 1111,1222,1333,1444. (Someone correct me if I am wrong)
