Question: A blind cave scorpion survives by catching millipedes. It needs to eat lots of millipedes to survive: a total of 800 body segments every day. If it's already eaten one millipede with 60 segments and 2 millipedes that are twice as long, how many 50-segment millipedes does it need to eat to reach its daily total?
Answer: First, the number of segments in the 2 millipedes that are twice as long is 60 segments * 2 = 120 segments. Then one can multiply the segments by the 2 millipedes to find the total number of segments: 120 segments / millipede * 2 millipedes = 240 segments. In total, we then find the scorpion has eaten one 60 - segment millipede in addition to the 3 millipedes above for a total of 60 + 240 = 300 segments. So, the number of segments it still needs to eat are : 800 segments - 300 segments = 500 segments. Thus, it needs to eat an additional 500 segments / 50 segments / millipede = 10 millipedes. The answer is 10.

Q: One of the clubs at Georgia's school was selling carnations for a fundraising event. A carnation costs $0.50. They also had a special where you could buy one dozen carnations for $4.00. If Georgia sent a dozen carnations to each of her 5 teachers and bought one carnation for each of her 14 friends, how much money would she spend?
A: She wants to send a dozen carnations that cost $4 / dz to each of her 5 teachers, so 4 * 5 = $20. She has 14 friends and she knows a dozen carnations is cheaper than buying 12 single carnations. So 14 - 12 = 2 single carnations are needed. A single carnation cost $0.50 so 2 * .50 = $1.00. All total she will spend 20 + 4 + 1 = $25.00 on carnations. The answer is 25.
Question: Hilton had a box of 26 marbles that he was playing with. He found 6 marbles while he was playing, but afterward realized that he had lost 10 marbles. Lori felt bad and gave Hilton twice as many marbles as he lost. How many marbles did Hilton have in the end?
Answer: Hilton had 26 marbles + 6 marbles - 10 marbles = 22 marbles. Lori gave Hilton 2 * the 10 marbles that he lost = 20 marbles. In total Hilton had 22 marbles + 20 marbles = 42 marbles. The answer is 42.
