Sarah blends coffee for Tasti-Delight. She needs to prepare 170 lbs of blended coffee beans selling for $3.59 per pound. She plans to do this by blending together a high-quality bean costing $5.00 per pound and a cheaper bean at $2.00 per pound. To the nearest pound, find how much high-quality coffee bean and how much cheaper coffee bean she should blend.
amount of expensive coffee --- x
amount of cheaper coffee --- 170-x
5x + 2(170-x) = 3.59(170)
should be easy to solve for x, then sub back in my definitions.
