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
