This is exponential growth. Use the formula P = 14000 (1+0.025)^5.
Note that (1+0.025)^5 = 1.025^5 = 1.131. Mult. the given population, 14000, by this factor to find the answer. Then round off your answer to the nearest whole number.
Note that
- 12=2·2·<u>3</u>;
- 20=2·2·5;
- 36=2·2·<u>3</u>·3.
The common factors of these three numbers are 2, 2. Also numbers 12 and 36 have one more common factor <u>3</u>, then the least common multiple is
LCM(12,20,36)=2·2·<u>3</u>·5·3=180 sec=3 min (here first you write all common factors between all three numbers, then between two numbers and at last all remaining factors).
Answer: all three experiments will need to be checked after 3 minutes passed, then after 6 minutes passed, then after 9 minutes passed and so on.
