Some scientists believe that the average surface temperature of the world has been rising steadily. The average surface temperature can be modeled by
T = 0.02t + 15.0
Use the equation to predict the average global surface temperature in 2090. (Round your answer to the nearest degree.)

W have this formula for the average temperature and are asked to find its value for the year 2090. 
So our t value is t= 2090
If we plug this into the formula, what value do you find for T?
