Use the equation for exponential decay we learned in class this week along with the percent decrease your calculated in part (b) to determine the half-life of naproxen. (In other words, how long does it take for the naproxen level to decrease to half of its original level. If the original tablet has 220mg, then half of that amount would be 110mg.) Hint: you will need to use logs. Include your calculations and overall result in your Excel workbook. (2 points)
