The amount of light emitted from a battery indicator bulb pulses while the battery is charging. This can be modeled by the equation y = 60+60sin[(pi/4)t] , where y is the lumens emitted from the bulb and t is the number of seconds since the beginning of a pulse. At what time will the amount of light emitted be equal to 110 lumens?

    mhh, aren't we just solving
    60 + 60sin[(π/4)t] = 110 ?

    sin[(π/4)t] = .833333
    make sure your calculator is set to radians
    [(π/4)t] = .98511
    t = .....

    let me know what you got
