Chapter Four: (Summary) Grant returns Miss Emma and his aunt to home. He leaves to go to Bayonne. This is the closest town to them. There are approximately 6000 people in Bayonne and the courthouse and jail are located here. Grant goes to the Rainbow Club, a bar for black people.

She, too, is a teacher. The purpose for visiting her is to let her know about being asked to visit Jefferson in jail. He wat someone to agree with him that it's a stupid idea. However, she agrees that he should go. Notes:

The interest rate \( r \) required to increase your investment \( p \) to the amount \( a \) in \( t \) years is found by \( r=\left(\frac{a}{p}\right)^{\frac{1}{t}}-1 \) Find the interest rate \( r \) for \( p=2700, a=6,400 \) and \( t=3 \). Round to the nearest hundredth.

Write \( 6.542 \times 10^{7} \) in decimal form
