<span>The equation that shows the cost of a mix of Arabica and Robusta beans is: 700 A + 1,200 R = 1,000,000. We know that a mixture contains 1,000 pounds of Arabica beans ( A = 1,000 ). So: 700 * 1,000 + 1,200 R= 1,000,000; 700,000 + 1,200 R = 1,000,000 ; 1,200 R = 1,000,000 - 700,000 ; 1,200 R = 300,000 ; R = 300,000 : 1,200 ; R = 250. Answer: There should be: R = 250 pounds.</span>
