Julia and her husband own a coffee shop. They experimented with mixing a City Roast Columbian coffee that cost $7.30 per pound with French Roast Columbian coffee that cost $8.30 per pound to make a 10-pound blend. Their blend should cost them $7.40 per pound. How much of each type of coffee should they buy? Pounds of City Roast coffee = Pounds of French Roast coffee = 11:59 Jotham needs 10 liters of a 30% alcohol solution. He has a 10% and a 60% solution available. How many liters of the 10% and how many liters of the 60% solutions should he mix to make the 30% solution? Liters of 10% solution= Liters of 60% solution= A scientist needs 4.4 liters of a 12% alcohol solution. She has available a 21% and a 10% solution. How many liters of the 21% and how many liters of the 10% solutions should she mix to make the 12% solution? Liters of 10% solution= Liters of 21% solution= Julia and her husband own a coffee shop.
