Total cost for the trip = $800.
Let x = original number of friends.
Therefore the equally shared cost of the trip for each friend is $800/x.
After 2 friends drop out, the cost for each friend increases to $800/(x-2).
The increase in cost for each remaining friend is $20, therefore
Divide through by 20.
Cross multiply.
x(x - 2) = 80
x² - 2x - 80 = 0
(x + 8)(x - 10) = 0
x = -8 or 10
Reject x = -8 because we cannot have a negative number for friends.
x = 10
Answer: There were 10 friends in the original group.
Answer:
C. some factors that are not measured or observed may affect the curve.
Explanation:
a lot of unforeseen circumstances might occur. these occurrences would not be measured in the estimated demand curve. this would lead to the estimated demand curve not matching the actual demand curve.
for example, the factors affecting the demand for bread are ; price, income, price of a substitutes. these are included in estimating the demand curve for bread. Assume that a study comes out stating that bread is harmful to the health.this reduces the demand for bread. this study wasn't anticipated and included in estimating the demand curve. as a result, the actual data would differ from the estimated data
Answer:
(B) the macroeconomy
Explanation:
The condition of the macroeconomy would exert the most influence of a firm's decision to hire more workers. As economic growth increases and demand grows, the firm is likely to hire more workers to meet increasing demand for its goods. On the other hand, in an economic recession, the firm is likely to hire less and even lay off its existing workers as demand for its goods reduces.
Option A is incorrect as a firm would not hire more workers even at low wage levels if the economy is in a recession. Option C is incorrect as the level of a firm's income would likely not be considered in its hiring decision if demand for its goods was very high. Option D is incorrect as the household income would likely not be considered by the firm in its hiring decision.

Answer:
C. All else being equal, the growth rate of the dividends is greater than 2%
Explanation:
The formula to calculate the fair price of a stock with a constant growth in dividends is as follows,
- P = D1 / r-g
- Where D1 is the dividend next period
- r is the required rate of return
- g is the growth rate in dividends
- P = 1.5 / 0.1 - 0.02 = 18.75
- We are taking 1.5 as D1 as it is the dividend per share DeepMind will pay next year.
So, we will be willing to pay more than 18.75 if the fair price per share today is greater than 18.75. We check all the 3 options.
A. say the required rate is 10.1%
- P = 1.5 / (0.101 - 0.02) = 18.52
- So if the required rate of return increases from 10%, the fair price per share is falling and we will be willing to pay less than 18.75 per share.
B. P = 1.2 / (0.1 - 0.02) = 15
- If D1 = 1.2,the fair price per share will be 15 which is less so we will not be willing to pay more than 15 for such share.
C. Say the growth rate in dividends is 2.1%
- P = 1.5 / (0.1 - 0.021) = 18.99
- The fair price per share increased to 18.99 if the growth rate in dividend increases by 0.1 percentage point. Thus, C is the correct answer
