(b) New technology enables Melvin Capital to perform one additional type of technique: technique C: multiplying the price by 1/4 With this additional technique, how many different sequences of techniques are there for Melvin Capital to drive the price down to exactly $5? 7. The Count is back and he has to choose a new 7-digit phone number. Again, we wants it to have the property that the digits are non-increasing. How many phone numbers are there? 8. Consider connected graphs with n labeled vertices such that the degree of each vertex is less than 4. How many such graphs have an Eulerian tour?
