There are six peregrine falcons and 40 pigeons nesting in Malcolm's skyscraper. Each pigeon has 6 chicks. If the peregrines eat 30% of the pigeons, how many pigeons are left?
Thoughts? Step-by-step reasoning:
First find the total number of chicks: 40 pigeons * 6 chicks / pigeon = 240 chicks. Then add that to the number of adult pigeons to find the total number of pigeons: 240 chicks + 40 pigeons = 280 pigeons. Then multiply that number by 30% to find the number of pigeons that were eaten: 280 pigeons * 30% = 84 pigeons. Then subtract that number from the total number of pigeons to find the number that are left: 280 pigeons - 84 pigeons = 196 pigeons.
Thus, the answer is 196.
