<human>:  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?
<bot>: Define a variable ** Let x represent the number of Chevys
How many Fords does Jim have? ** Fords:3+2x
How many Buicks does Jim have? ** Buicks:4(3+2x)=12+8x
Write an equation ** Total:x+3+2x+12+8x=301
Combine like terms ** 11x+15=301
Subtract 15 ** 11x=286
Divide by 11 ** x=<<26=26>>26
How many Buicks does Jim have? ** Buicks:12+8(26)=220
