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.
So in 1 hour they will be 48+55=103 miles apart
how many hours will it be in 618
103 times x hours=618
divide both sides by 103
x=618/103
x=6
the answer is 6 hours
20 rows * 15 seats per row=300 seats in section J
300 seat in Section J * $18 per ticket= $5,400 in revenue
Answer:

Step-by-step explanation:
Given
x² - 3x
To make the expression a perfect square
add ( half the coefficient of the x- term )²
x² + 2( -
)x +
, thus
x² - 3x + 
= (x -
)² ← a perfect square
