Using an exponential function, it is found that the amounts deposited at the end of each month are given by:
- At the end of the first month, she deposits $110.
- At the end of the second month, she deposits $121.
- At the end of the third month, she deposits $133.1.
- At the end of the fourth month, she deposits $146.41.
<h3>What is an exponential function?</h3>
An increasing exponential function is modeled by:
In which:
- A(0) is the initial value.
- r is the growth rate, as a decimal.
In this problem, we have that A(0) = 100, r = 0.1, hence the equation for the amount deposited after t months is:
Then, for each of the first four months:

Step-by-step explanation:
APR = annual percentage rate.
Since Pete is borrowing the money for one week, the APR must be divided into a daily interest rate before we can figure out how much he'll pay for the loan.
There are 365 days in a year. Divide the APR by 365 to find the daily interest rate.
The daily interest rate of the loan will be 1.643%.
The following equation is used to find the total interest payment:
A represents the total amount paid in interest. P represents the amount borrowed for the loan. r represents the daily interest rate. t represents the amount of days the loan will last.
Plug in your values into the equation.
Rounded to the nearest hundredths value, the total interest paid will be
$12.14.
Compare the total amounts paid for both loans.
$12.14 < $45
The better deal is the
loan with the 600% APR.

I think the answer would be the fourth answer or the second answer.
sorry if its not the correct answer.
Step-by-step explanation:
Sarah had a loss of $27 for the four days.
Step-by-step explanation:
Given,
Loss on Thursday = $19
Loss on Friday = $12
Loss on Saturday = $11
Profit on Sunday = $15
Lets suppose loss as negative amount and profit as positive amount.
Adding all the loss and profit =
Total =
Total =
As we supposed negative amount as loss, therefore,
Sarah had a loss of $27 for the four days.
