If 9% of a number equals 30, find 27% of that number.

90

Step-by-step explanation:

Rewriting what is given: (0.09)(n)=30

Where n is the unknown number and 0.09 is the numerical form of 9%. Solving for n gives:

n=(30/0.09)=333.333

27% as a number is 0.27. So 27% of n is:

(0.27)(n)=(0.27)(333.333...)=90

27% of that number is 90.

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time
