You divide the rate of growth into 70. In this case it is 2%. So the answer is 35.

RULE 1: To determine the doubling-time (d) for an exponentially-growing quantity, divide the annual percentage rate of increase (p) into 70.

d = 70/p [Rule 1]

where:

d = the time it takes for the quantity to double in size;

p = the annual increase expressed as a percentage
