Jake owns two gas stations in town. The projected revenue of the first gas station for the next 12 months is
0.3t2 + 150t (0 ≤ t ≤ 12)
thousand dollars t months from now. The projected revenue of the second gas station for the next 12 months is
0.4t2 + 250t (0 ≤ t ≤ 12)
thousand dollars t months from now. Find an expression that gives the amount by which the revenue of the second gas station will exceed that of the first gas station in month t (0 ≤ t ≤ 12).
