The price per square foot in dollars of prime space in a big city from 2010 through 2015 is approximated by the function (0 ≤ t ≤ 5) R(t) = -0.553t³ + 3.301t² + 2.907t + 236.5 where t is measured in years, with t = 0 corresponding to 2010. (a) When was the office space rent lowest? Round your answer to two decimal places, if necessary. t = 0 years after 2010 (b) What was the lowest office space rent during the period in question? Round your answer to two decimal places, if necessary. dollars per square foot 263.5 (c) When was the office space rent highest? Round your answer to two decimal places, if necessary. t = 4.38 years after 2010 (b) What was the highest office space rent during the period in question? Round your answer to two decimal places, if necessary. dollars per square foot
