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.
