For 1995 through 2005, the revenue "R" (in dollars) and the cost "C" (in dollars) of producing a product can be modeled by:
R = (1/4)t^2 + 400
and
C = (1/12)t^2 + (13/4)t + 200
where "t" is the number of years since 1995. Write an equation for the profit earned from 1995 to 2005. (Hint: profit = revenue - cost)

Question

For 1995 through 2005, the revenue "R" (in dollars) and the cost "C" (in dollars) of producing a product can be modeled by:

Okay so what is the total revenue at 2005

anonymous · Answer

you're only supposed to write an equation.

dan815 · Answer

Okay then 
Profit = Revenue - cost
          =[ (1/4)t^2 + 400 ] - [(1/12)t^2 + (13/4)t + 200]

dan815 · Answer

simplify that further
