The county fair charges $1.25 per ticket for the rides. jermaine bought 25 tickets for the rides and spent a total of $43.75 at the fair. jermaine spent his money only on ride tickets and fair admission. the price of the fair admission is the same for everyone. use c to represent the total cost and r to represent the number of ride tickets

(b)write a linear equation that can be used to determine the cost for anyone who only pays for ride tickets and fair admission. (think slope-intercept form)

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."
