Right Riemann Sum From Tabular Data

Question

A tank contains 50 liters of oil at time $$t = 4$$ hours. Oil is pumped into the tank at a rate $$R(t)$$, in liters per hour, where $$t$$ is measured in hours. Selected values of $$R(t)$$ are given in the table.

| $$t$$ (hours) | 4 | 7 | 12 | 15 |
|-------------|---|---|----|----|
| $$R(t)$$ (liters/hour) | 6.5 | 6.2 | 5.9 | 5.6 |

Using a right Riemann sum with three subintervals indicated by the data in the table, what is the approximate number of liters of oil in the tank at time $$t = 15$$ hours?
