Solve the problem.The weight of a ram can be estimated by the function W(t) = -7.3 + 304.8e-e(-0.00956(t - 131.9)),where t is the age of the ram (in days) and W(t) is the weight of the ram (in kg). If a particular ram is 50 days old, use differentials to estimate how much weight it will gain before it is 60 days old.
A. 3.8 kg
B. 7.5 kg
C. 7.9 kg
D. 7.1 kg
