Answer:
624000
Explanation:
Actually nvm about the clearer pic but since this is not charted on a graph pls dont hurt me if im wrong but it appears that the inflation rate by july 2017 would be about 1.8 so you take 780000 times 1.8 which is 1404000 then subtract the initial price paid so 1404000 minus 780000 which equals 624000 this would be your profit if the inflation rate is indeed 1.8 but as i said i cant really see as its not on a graph
Hope this helps :)
