a coffee shop purchased 60 pounds of Guatemalan coffee beans and 90 pounds of
Nicaraguan coffee beans and the total price was $180.00 what was the price per pound for each different coffee bean?

I love this problem because I've been to both of those countries.
Now, I'm going to write that 60G + 90N = 180
In the previous equation, the G stands for the price of Guatemalan coffee, per pound. N, of course, is the same thing for Nicaraguan coffee. Now I can use algebra to solve for either G or N:
G = 3 - 1.5N and also...
N = 2 - (2/3)G
Remember, there are multiple possibilities because the cost of each coffee depends on the cost of the other.
