A very small tumor of initial size M is observed every 10 days, and over each ten-day period, it has grown 70% larger.
(a) Write the formula representing size of tumor after t days (t = 0, 10, 20, . . .)
(b) On which day will we at last observe that tumor is more than ten times its original size? (Suppose that observations are strictly periodically conducted as specified.)
(c) How many times greater than original size will tumor be on day 100?
