A coin box contained some 20 cents and 50 cents coins in the ratio 4:5. When 16 50 cents coins where taken out and replaced by some 20 cents coins the ratio then became 8:7. T he total value of 20 cents coins added was the same as the total value of the 50 cents coin taken out. Find the sum of money in the coin box?

I try to make the units in the end the same so the 20 cents section is multiplied by 7, and the 50 cents section is multiplied by 8.
