Answer:
<u>A. elastic;</u> <u>inelastic </u>
Explanation:
Price elasticity of demand refers to degree of responsiveness of quantity demanded of a good with respect to a change in the price. It is mathematically expressed as:

wherein dQ= Change in quantity demanded
dP = Change in price
p = Original Price
q = Original quantity
Total revenue refers to total receipts of a firm from the sale of a good.
When price elasticity of demand is less than 1, it refers to inelastic demand which further means, the change in quantity demanded is less w.r.t change in price.
Similarly, when price elasticity of demand is greater than 1, it signifies change in quantity demanded is more w.r.t change in the price.
In the given case, the cashier thinks lowering prices will increase the total revenue. This indicates the cashier believes the demand to be elastic.
Similarly, the friend's belief of increased prices leading to increased total revenue signifies inelastic demand.
Answer:
B. $228,122.
Explanation:
Number of quarters = 3 * 4 = 12
Quarterly interest rate = 12%/4 = 3%
From the table, the correct discounting factor for the future value (FV) = 1.42576
We then have:
FV = $160,000 * 1.42576 = $228,122
Therefore, the maturity value of the CD is $228,122.

Answer: 45%
Explanation:
Standard deviation for the portfolio will be a weighted average of the standard deviations of the individual assets.
Risky asset has standard deviation of 20%. Assume the weight is x.
Treasury bills have a standard deviation of 0 as they have no risk. Assume their weight is y.
Target Standard deviation is 9%.
Formula would be:
9% = (x * 20%) + (y * 0%)
20%x = 9%
x = 9% / 20%
x = 45%
