daniela and sorin have each recently received some money , daniela won a cash prize and sorin received an inheritance , daniela had two options to choose from to receive her winnings , in both options , she receives, a payment on the first day of each month for three years, option a)each payment is $4200 option b)the first payment is $1500, in each month which follows,the payment is 4%more than the previous month , find the total amount daniela would receives if she chooses option a , optionb

We will calculate the total amount Daniela would receive under each option.

### Option A: 
In this option, Daniela receives $4,200 every month for three years.

Since there are 12 months in a year, over 3 years, there are:
\[
3 \times 12 = 36 \text{ months}
\]

Thus, the total amount she would receive in this option is:
\[
4200 \times 36 = 151,200
\]

### Option B: 
In this option, the first payment is $1,500, and each subsequent payment increases by 4%.

This describes a geometric sequence where:
- The first term $ a_1 = 1500 $
- The common ratio $ r = 1 + 0.04 = 1.04 $
- The number of terms $ n = 36 $ (because the payments are made monthly for 3 years).

The formula for the sum of the first $ n $ terms of a geometric sequence is:
\[
S_n = a_1 \times \frac{1 - r^n}{1 - r}
\]

Substituting the values:
\[
S_{36} = 1500 \times \frac{1 - (1.04)^{36}}{1 - 1.04}
\]
Now, calculating $ (1.04)^{36} $ and the sum:

\[
S_{36} = 1500 \times \frac{1 - 3.999}{-0.04}
\]
\[
S_{36} = 1500 \times \frac{-2.999}{-0.04}
\]
\[
S_{36} = 1500 \times 74.975
\]
\[
S_{36} \approx 112,462.5
\]

### Conclusion:
- In **Option A**, Daniela would receive **$151,200** in total.
- In **Option B**, Daniela would receive approximately **$112,462.50** in total.

### Tip:
Geometric series are useful for solving problems involving successive percentage increases or decreases, such as compound interest or payments increasing by a fixed percentage.
