Question
  1. Mad Dr. Frankenstein has some 45% and some 32% “life essence” solutions left over from some failed experiments. How much of each of these should he mix to create 130 liters of the 40% “life essence” solution he feels will finally be successful

  2. Count Dracula and Frankenstein’s monster were celebrating Halloween with friends. At midnight, the monster left for his long walk home limping at a rate of 4.8 km/hr. Two hours later, the Count found one of the monster’s neck bolts in a bowl of guacamole. He knew he had to act fast, so he took off after him at a rate of 12.48 km/hr. How long will it take the Count to catch up to the monster?

    (Assume they are travelling the exact same route.) (Rate • Time = Distance)

  3. Together the Mummy and Wolfman can rake their yard in 18 minutes. Alone, the Mummy needs 15 minutes longer to rake the yard than Wolfman needs when raking by himself. How much time does it take for each of them to rake the yard alone?
