Each year a store decreased the price of a certain model of TV by $35. If the price in 2001 was $1950, what was the price in 2009?
The period the store had the TV was 2009-2001= <T>subtract(2009, 2001)=8 years.
The TV decreased by $35/year * 8 years = $<T>multiply(35, 8)=280
So the price in 2009 was $1950 - $280 = $<T>subtract(1950, 280)=1670
