coffee bean

One kind of coffee bean costs $6/kg and another costs $8/kg, How many kilograms of each should be mixed to pro?
One kind of coffee bean costs $6/kg and another costs $8/kg, How many kilograms of each should be mixed to produce 10 kg worth $6.50/kg?
Let x be the amount of $6/kg mixture and 10 - x be the amount of $8/kg mixture. Recall that the price of a mixture is equal to the amount of the mixture times it's price. Since $6 is the price per kg of mixture 1 and we have x kg, it will cost 6x to produce. Since mixture 2 is $8/kg and the amount is (10 - x) kg, it's price will be 8(10 - x). The total mixture will be worth $6.50/kg with 10 kg giving $65 worth of total mixture. This gives:
6x + 8(10 - x) = 65
==> 6x + 80 - 8x = 65
==> -2x + 80 = 65
==> -2x = -15
==> x = 7.5
Therefore, 7.5kg of $6/kg mixture and 10 - 7.5 = 2.5kg of $8/kg mixture should be used.
I hope that helps!

Coffee Bean Guys - Episode 1 of 4
Do you think the mass of a jelly bean would be the same as the mass of a coffee bean?
i'm doing a project that requires the mass of a single coffee bean and i can't find that figure anywhere. do you think it would be reasonably similar to that of a jelly bean?
Roasted coffee beans are dry, so they're probably lighter. Go down to your nearest Starbuck's and ask them for a bean, and weigh it.
