Answer:
19.9
Step-by-step explanation:
we can write the following equation
18000(1.02)^n
where n is the number of years
so we have
26700=18000(1.02)^n
solve for n
1.483=1.02^n
use logs to solve for n
n=19.9
C is the answer I got it right
Step-by-step explanation:
From a, the original number is 100x the new number.
So,if the new number is 1unit --> the original is 100x 1unit --> 100units
Add the two numbers together --> 1unit + 100units --> 101 units
We also know that the difference between the two numbers is 136.62
So 100units - 1unit --> 136.62
99units -> 136.62
1unit --> 1.38
101units --> 139.38
