    To calculate work you need to find the change in energy which can be found by multiplying force by displacement and in this problem, the value of force would be 7105N (Mass of balloon * Earth's acceleration) then multiplied by 250m (1275m-1025m) then you can find that the total work is 1,776,250 joules
