1)Gabe a nucear physicist needs 30 liter of a 60% acid solution. He currently has
a 40% solution and a 70% solution. How many liters of each does he need to make
the needed 30 liters of 60 % acid solution?

2)Sarah Meeham blends coffee for Tasti-Delight. She needs to prepare 130 pounds of blended coffee beans selling for $4.40 per pound. She plans to do this by blending together a high-quality bean costing $5.25 per pound and a cheaper bean at $2.50 per pound. TO the nearest pound, find how much high-quality coffee bean and how much cheaper coffee bean she should blend.
