$10 lb how many lbs. of sumatra and how many lbs. of arabian Coffee Beans should u use?
i probably should use an equation to figure this out. that would please the professor
You can always use algebra for this, but one easier way to reason it out is to think about how far from the $10 average your two varieties are. The $12 coffee is $2 away from the desired price, while the $4 coffee is $6 away from the target price. That means that in order to get an average price of $10, you have to have three times as much of the $12 coffee.
Given that you have a total weight of 20 lbs, the only way to do this is to have 15 lbs of the arabian and 5 lbs of the sumatra.
Best wishes!

What can I do with the left over coffee I have everyday? Does anyone have a recipe or an idea to use left over coffee? Maybe in a meal once a week or in a drink? Thanks.
