Jim collects model cars, and he has 301 models total. Jim has 4 times as many Buicks as Fords, and 3 more than twice the number of Fords than Chevys. How many Buicks does Jim have? Let's answer step by step:
Let x represent the number of Chevys. Fords:3 + 2x. Buicks:4(3 + 2x) = 12 + 8x. Total:x + 3 + 2x + 12 + 8x = 301. 11x + 15 = 301. 11x = 286. x = 26. Buicks:12 + 8(26) = 220. The answer: 220.
