Answer:
1,000,000
Explanation:
As there are constant returns to scale the cost to produce a greater output will grow following a linear fucntion thus,
if 100 units units are produced at a cost of 200,000 dolllars
then 500 units will be produced five times that amount:
200,000 x 500/100 = 200,000 x 5 = 1,000,000
The total cost for 500 units will be a million dollars
