The four girls washed the neighbor's dog for 50 cents. They didn't know how to divide the money, so the dog owner said: "I will give the four of you 4/5 of the total amount. To the first one to tell me how much that is, I will give 1/2 of the other 1/5" . If someone gave the dog owner the right answer, how did the money get divided up?
+1223 The four girls initially received 4/5 * 50 = 40 cents to divide among themselves. Whoever got the question correct got an extra 1/2 * 1/5 * 50 = 5 cents.
