A supercapacitor is an electrical energy storage device. A supercapacitor, initially charged to 9.8 thousand millivolts, supplies power to an emergency beacon. The power draw from the load causes the capacitor to lose 4.4% of its charge every minute. When the charge drops below 7 hundred millivolts the beacon will cease functioning. How long will the beacon last after it is activated (your final answer should be in minutes). Round your answer to the nearest minute.
