The rate of healing, A′(t) (in square centimeters per day), for a certain type of skin wound is given approximately by the following table:

(A) Use left and right sums over five equal subintervals to approximate the area under the graph of A′(t) from t = 0 to t = 5.

(B) Replace the question marks with values of L₅ and R₅ as appropriate:
