    the equation given is 700A+1200R=1,000,000 why the cost should be fixed at 1,000,000 is beyond me, but anyway that is what it says then it says A=1000 so now the equation is 700×1000+1200R=1,000,000 or 700,000+1200R=1,000,000 which i would solve in two steps 1) subtract 7000,000 to get 1200R=300,000 2) then divide by 1200 to get R=250
