Answer:

(a) Expected gain = 30

(b) Standard deviation = 66.03

Explanation:

From the question, we are given the following:

Probability of loss = 10%

Loss amount = $150

Probability of Saving = 100% - Probability of loss = 100% - 10% = 90%

Saving amount = $50

Therefore, we proceed as follows:

a) If she books the cheaper​ flight, what can she expect to​ gain, on​ average?

This can be calculated as follows:

Expected gain = (Probability of loss * (-Loss amount)) + (Probability of Saving * Saving amount) = (10% * (-150)) + (90% * 50) = -15 + 45 = 30

b) What is the standard​ deviation?

Standard deviation can be described as a measure of the amount of variation a set of values. This can be calculated from the variance as follows:

Variance = (Probability of loss * (-Loss amount - Expected gain)^2) + (Probability of Saving * (Saving amount - Expected gain)^2) = (10% * (-150 - 50)^2) + (90% * (50 - 30)^2) = (10% * (-200)^2) + (90% * (20)^2) = (10% * 40,000) + (90% * 400) = 4,000 + 360 = 4,360

Standard deviation = Variance^0.5 = 4,360^0.5 = 66.03

Summarize how compound interest helps you to accumulate savings even faster.
yulyashka [42]

Answer:

The magic of compound interest happens in a way  that the more you put in, the faster your money grows.

Explanation:

The magic of compound interest happens in a way  that the more you put in, the faster your money grows. The interest you earn on the amount you save also earns interest and this snowballing effect makes you accumulate your savings even faster. For example, if you deposit $100 in a savings account that pays 5% interest per year. At the end of the year, you account will have (5%*100= 5) plus the $100 you deposited, coming to a total of $105. At the end of the second year, your $5 interest earned in year 1 will earn another 5% interest and so will the $100 you initially deposited.

Present value (PV) is sum of all cash flows discounted at 7%.

(a) Annual decrease = $2,000

PV is computed as follows.

Year Cash Flow ($)     PV Factor at 7%     Discounted Cash Flow ($)

               (A)                     (B)                     (A) x (B)

1 20,000 0.9346 18,692

2 18,000 0.8734 15,722

3 16,000 0.8163 13,061

4 14,000 0.7629 10,681

5 12,000 0.7130 8,556

6 10,000 0.6663 6,663

7 8,000 0.6227 4,982

8 6,000 0.5820 3,492

9 4,000 0.5439 2,176

10 2,000 0.5083 1,017

PV ($) = 85,041
