Answer:
£.0.6875 per USD
Explanation:
PPP stands for purchasing power parities. It is actually the rate of currency conversion.
As per the given information, the price level recently increased by 20% in England while falling by 5% in the United States, so the net increase in the U.S. dollar would be (20+5)=25%.
This can be taken as that now 20% more pounds shall be needed to purchases the same U.S. goods.
Hence the new exchange rate would be:
= 1.25 x £0.55/$1 = £.0.6875 per USD
