Ben and Mildred's Stables used two different independent variables (trainer hours and number of horses) in two different equations to evaluate the cost of training horses. The most recent results of the two regressions are as follows:

What is the estimated total cost for the coming year if 14,700 trainer hours are incurred and the stable has 310 horses to be trained, based upon the best cost driver?
A) $7,992.85
B) $300,276.50
C) $332,343.45
D) $13,995,671.20
