Sarah Meeham blends coffee for Tasti-Delight. She needs to prepare 190 pounds of blended coffee beans selling for $4.55 per pound. She plans to do this by blending together a high-quality bean costing $5.50 per pound and a cheaper bean at $3.25 per pound. To the nearest pound, find how much high-quality coffee bean and how much cheaper coffee bean she should blend.

Pounds of high-quality coffee =H

Pounds of cheaper coffee        =190 - H

 

5.50H + 3.25[190 - H] =190*4.55, solve for H

H = ~110 pounds of high-quality cofffee

190 - 110 = 80 pounds of cheaper coffee.
