Answer:

12 pounds of Kenyan French Roast coffee

8 pounds of Sumatran coffee

Step-by-step explanation:

if you use x pounds of Kenyan French Roast coffee and y pounds of Sumatran coffee then you know that

10x+10y=200

11x+10y=212

x=12

y = 20-x = 20-12 = 8

12 pounds of Kenyan French Roast coffee

8 pounds of Sumatran coffee
