Answer:
it will purchase
96 dollars of Arabian Mocha
and 48 dollars of Colombian Decaf
Explanation:
we build the equation system:
[tex]144 = x + y \\ x = 2y[/tex]
we replace the second expression on the first and solve for y
144 = (2y) + y
144 = 2y + 1y
144= 3y
144/3 = y
48 = y
now we solve for x
x= 2y
x= 2 times 48 = 96
