Hi, 

Let x represent the kilograms of the brazillian coffee

Then (216kg - x) would represent the kilograms of the venezuelan coffee

question states***

$12/kg*x + $16/kg(216kg-x)= $15/kg*216kg

$1/kg/kg*216kg = $4x

54kg = x, the amount of the brazillian coffee

162kg the amount of the venezuelan coffee  (216kg-54kg)



checking our answer

12*54 + 16*162 = 648 + 2592 = 15*216 =  3240
