The admission to a local carnival is $6.50 per person and $2.50 for each ride. jenna wants to know much it will cost her to ride a certain number of rides at the carnival. which equation can she use to create a table with this information (where  p  is the number of persons,  r  is the number of rides, and  t  is the total cost of admission and rides)?   6.50p  + 2.50 =  t6.50 + 2.50r  =  t6.50r  + 2.50 =  t6.50 + 2.50p  =  t

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."

Which of these equations, when solved, gives a different value of x than the other three? a9.1 = -0.2x + 10 b10 = 9.1 + 0.2x c10 – 0.2x = 9.1 d9.1 – 10 = 0.2x
