The cost of coffee is determined by the type of coffee beans that are mixed together. The cost of a local mix of Arabica and Robusta beans is modeled by the equation below, where A = the pounds of Arabica and R = pounds of Robusta: 700A + 1200R = 1,000,000 If a mixture contains 1000 pounds of Arabica beans, how many pounds of Robusta beans should be in the mixture?

Ok so we can plug in 1000 for A and then solve for R 700(1000) + 1200R = 1,000,000 700,000 + 1200R = 1,000,000 1200R = 300,000 R = 250
