Answer:

ln 3

Step-by-step explanation:

Using the rules of logarithms

• log x^{n} ⇔ n logx

• log x - log y = log (\frac{x}{y} )

Given

3 ln3 - ln9, then

= ln 3³ - ln 9

= ln 27 - ln 9

= ln (\frac{27}{9} ) = ln 3

An insurance agent receives 15% of the cost of each insurance policy she sells
HACTEHA [7]
In this question there are several important information's provided. Using these information's it is easy to get the answer to the question asked. Firstly it is already informed that the insurance agent gets a commission of 15% of the policy price for every policy sold. The agent sells a policy of $300.
Now we can write the equation as:
15% of $300 = [(15/100) * 300] dollars
                     = ( 15 * 3) dollars
                     = 45 dollars
So the agent gets a commission of $45 for selling a policy worth $300

A family member has some five dollar bills and one dollar bills in their wallet. Altogether she has 18 bills and a total of $62.
Pepsi [2]
X - the number of five dollar bills
y - the number of one dollar bills

She has 18 bills in total.
x+y=18 \\ y=18-x

She has $62.
5x+y=62 \\&#10;y=62-5x

Set both expressions equal to each other:
18-x=62-5x \\&#10;-x+5x=62-18 \\&#10;4x=44 \\&#10;x=11 \\ \\ y=18-x=18-11=7

She has 11 five dollar bills and 7 one dollar bills.
