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=a pound of arabica and R= a pound of robusta. 700A+1200R=1000000 if a mixture contains 1000 pounds of arabica beans how many pounds of robusta beans should be in the mixture
