The temperature of a certain cup of coffee 10 minutes after it was poured was 120 degrees Fahrenheit. If the temperature "F" of the coffee "t" minutes after it was poured can be determined by the formula F = 120(2^(-at))+60, where "F" is in degrees Fahrenheit and "a" is a constant, then the temperature of the coffee 30 minutes after it was poured was how many degrees Fahrenheit.
