The demand of computers is surely increasing in recent years. A survey shows that this
phenomenon can be calculated by the function
D(t) = 23.575 +2.71 . Here, D(t) represents the
demand (measured in millions) and represents the
time (measure in years). How many years will it
take for the demand of computers to reach 132.2
million Round your answer to the nearest tenth.
