15. The power that a hydroelectric dam generates can be modeled using the formula

where P is the power the dam generates, in megawatts; Q is the flow rate of the river, in cubic meters per second; h is the height of the dam, in meters; and γ is the weight per unit volume of water, in newtons per cubic meter. According to this model, which of the following is closest to the power, in megawatts, generated by a dam that is 25 meters high if the flow rate is 8.0 cubic meters per second and the weight of water is 9,790 newtons per cubic meter?
