1. players from the local little league plans to hold a car wash as a fundraiser. if they charge
$5 per car, how many cars do they need to wash to earn at least $250 dollars?

a. write an inequality to represent this situation, using x to represent the number of cars the
players need to wash.

b. solve the inequality by isolating the variable. show all work leading to your answer.

graph the solution on the number line. be sure to include number labels to show the
values of x on the number line.

d. write 1-2 sentences to explain what the solution to the inequality represents for this
situation.

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."
