She plans to do this by blending together a​ high-quality bean costing ​$6.50 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.
She should blend ______Ibs of high quality beans.

Answer 1

Answer:

Step-by-step explanation:

Let p= Pounds of Expensive $6.50 coffee

Then 140 - p = Pounds of $2.00 coffee

6.5p + 2(140-p) = 4.89(140)

Multiply through the parenthesis, combine like terms and then solve for p.

Then you know how many pounds of $6.50 coffee to use.

Subtract that from 140 to get how many pounds of $2.00 coffee the use.
