Question

Barstucks is making a new coffee blend. The company bought 50lbs. of Kona beans at $34.95 per lb. and plans to mix these beans with Columbian beans that sell for $7.99 per lb. wholesale. If Barstucks wants its cost of the blend to be $11.95 per lb., how many lbs. of Columbian beans should they buy?

Answer 1

C=number of pounds of Colombian required
then
50*34.95+C*7.99=(50+C)*11.95
Solve for C.
