    If there are x kg of Brazilian coffee, then there are (300-x)kg of Turkish coffee.
Now, work with the cost for each type of nut. They must add up to the totals cost.
5x + 8(300-x) = 7(300)
5x + 2400 - 8x = 2100
3x = 300
x = 100
So, you need 100kg of Brazilian and 200kg of Turkish.
ote that $7 is 1/3 of the way from %5 to $8. So, the cheap coffee is 1/3 of the final mix.
