Lizzy: A farm has 5 less than 9 times the amount of hens as roosters. If there are 75 total chickens, how many hens are there?.
Me: Hmmm, let me think. I think this is the detailed solution:
Let x represent the number of roosters. Number of hens:9x - 5. Total:9x - 5 + x = 75. 10x - 5 = 75. 10x = 80. x = 8. Number of hens: 9(8) - 5 = 67. Final answer: 67.
