Copy the problem from the lesson:

1. A store manager wishes to reduce the price on her fresh ground coffee by mixing two grades. If she has 50 pounds of coffee which sells for $10 per pound, how much coffee worth $6 per pound must she mix with it so that she can sell the final mixture for $ 8.50 per pound?

What Do I Know?

She has 50 lbs. @ $10 per pound

She needs ??? @ $6 per pound

The mixture will sell for $8.50 per pound

What Do I Want to Know?

how many pounds of coffee @ $6 per pounds

Assign Variables

Let B = pounds of better grade of coffee

Let L = pounds of lower grade of coffee

Let T = total pounds of coffee after mixing

Write a verbal Model:

Pounds of lower grade coffee + 50 lbs. of better grade coffee = total pounds of coffee.

How Do I Find the Components of the Verbal Model?

**Reiny**, Wednesday, November 17, 2010 at 4:58pmThere is no need to have all those variables, since there is only one, the amount of lower grade coffee defined by L

my equation would be

10(50) + 6L = 8.5(50+L)

and I got L = 30
