A tank contains 50 liters of oil at time t=4 hours. Oil is being pumped into the tank at a rate R(t) measured in liters per hour and t is measured in hours. Selected values of R(t) are given in the table. Using a right Riemann sum with three subintervals and data from the table, what is the approximation of the number of liters of oil that are in the tank at time t=15 hours?
114.9 Liters
