[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.

[Question]While at Wizards Park, Kate buys 3 magic wands, one for herself and two for her friends. When she returns she sells the wands to her friends for $5 more than she paid. If she collected $130 after the sale, how much money did each wand cost?
[Answer]Out of 3 wands purchased, Kate sold her friends 3 wands - 1 wand = 2 wands. For 2 wands she charged $130, so for 1 wand she charged $130 / 2 wands = $65 / wand. Since she charged $5 more for each wand than she paid, Kate paid $65 - $5 = $60 for each wand. The answer is 60.

[Question]If I'm 4 times older than Billy currently, and Billy is 4 years old, how old was I when Billy was born?
[Answer]I would currently be 4 * 4 = 16 years old, since I'm 4 times older than Billy's age of 4. Therefore, in order to find my age at Billy's birth we'd simply subtract Billy's age of 4 from my age, meaning I was 16 - 4 = 12 years old. The answer is 12.

[Question]Ivy baked 20 cupcakes in the morning and fifteen more cupcakes in the afternoon than in the morning. How many cupcakes did she bake?
