Question

Four friends have different numbers of cows on their farms. Jorge has 3 times as many cows as 
Carla. Marcus has half as many cows as Jorge. Dominique has 2 less than 4 times as many cows 
as Carla. How many cows does each person have if they have a total of 169 cows?

anonymous · Answer

x: cows of Carla
169 = 3 x + 3/2 x + 4x-2 + x
total = jorge + Marcus + Dominique + Carla

anonymous · Answer

169 = 6/2 x + 3/2 x + 8/2 x -2 + 2/2 x
169 = 9/2 x + 10/2 x -2
169 = 19/2 x -2

171 = 19/2 x

anonymous · Answer

19 x = 171 x 2
19 x = 342
x = 18

according to the calculations, carla has 18 cows
