    Simple maths that is making my head implode
    You have 1kg of unroasted green coffee beans at a cost of $7. When you roast this coffee you lose 20% of the original weight to produce only 800g of roasted coffee. How much is 1kg of roasted coffee? Please teach me this maths!

    You lost 20% by weight. What weight of green beans multiplied by X %(remainder) = 1Kg? You then can determine the additional cost to make 1Kg of roasted beans.
