Answer:

D) ln (60) = 4.094...

Step-by-step explanation:

Let's solve for x

We'll be careful because it's exponential.

5ex = 300

ex= 300/5

ex= 60

x = e^-1(60)

Let's note that this expression e^-1 is equal to In

x= In (60)

x = 4.0943

So the value of x is equal to 4.0943

Thank you.

Answer:

the percent reduction is <u>33.6%</u> and the number of people who were issued a parking ticket are <u>42</u>.

Step-by-step explanation:

Given:

Last month in the village of 125 people were issued a parking ticket.

This month only 83 people were issued one.

Now, to find the percent reduction from this month to last month and the number of people who were issued a Parking ticket.

So, the reduction of the number of people who were issued a Parking ticket from this month to last month are:

125 people - 83 people = 42 people.

Thus, 42 people reduction from this month to last month.

Now, to get the percent reduction:

$\frac{42}{125}\times 100.$

$=\frac{4200}{125}$

$=\ 33.6\%$

Therefore, the percent reduction is 33.6% and the number of people who were issued a parking ticket are 42.
