let the initial price be $100.Increase in price due to inflation = 45%Increased price = 45% of 100=45Price after increase = 100+45 =$145After the increase in price there is a drop in price .Drop in price due to inflation = 20%Drop in price = 20% of 145=29New price = 145-29=116Total increase in price = 116-100=16Overall there was an increase of 16%.
