Kirsten's work is shown below:

1 x 1.75 = 1.75
10 x 1.75 = 10.75
100 x 1.75 = 100.75
1,000 x 1.75 = 1,000.75

this is the correct pattern:

1 x 1.75 = 1.75
10 x 1.75 = 17.5
100 x 1.75 = 175
1000 x 1.75 = 1,750

what was her mistake?

Asays "we are both knaves" and b says nothing. exercises 24–31 relate to inhabitants of an island on which there are three kinds of people: knights who always tell the truth, knaves who always lie, and spies (called normals by smullyan [sm78]) who can either lie or tell the truth. you encounter three people, a, b, and c. you know one of these people is a knight, one is a knave, and one is a spy. each of the three people knows the type of person each of other two is. for each of these situations, if possible, determine whether there is a unique solution and determine who the knave, knight, and spy are. when there is no unique solution, list all possible solutions or state that there are no solutions. 24. a says "c is the knave," b says, "a is the knight," and c says "i am the spy."
