Previous year's budget was 12.5 million dollars. This year's budget is 14.1 million dollars. How much did the budget increase?
Last year's budget must be subtracted from this year's budget; 14.1 million - 12.5 million = 1.6 million. Because both numbers are millions, the 14.1 and 12.5 can simply be subtracted and million is additional to the answer.
