Answer: C 2.5%
Step-by-step explanation:
The "Rule of 72" is a easy way to calculate how much time an investment will take to double with a given fixed annual rate of interest.
Just we have to divide 72 by the annual rate of return(r), we can get a rough estimate of how many years it will take to double the initial investment .
Now, in given problem: Let 'r' be the rate of interest
Time to double the amount=29 years
Thus by rule 72 ,

Therefore, C is the right option.

Answer:
5a(6
-
)
Step-by-step explanation:
Given
30a
- 5
← factor out 5a from each term
= 5a(6
-
) ← in factored form
Y=4x+4
I think this is it u just have to simplify to get it to y=mx+b
