A certain drug raises a patient's heart rate, h, in beats per minute, according to the equation `h(x)=65+0.2x`, where x is the number of milligrams of the drug in the patient's bloodstream. After t hours, the level of the drug in the patient's bloodsteam decrease exponentially according to the equation `x(t)=512(0.7)^(t)`. After 5 hours, what is the number of beats per minute in the patient's heart rate, correct to the nearest whole number?
