Final Answer:
The difference between the 52-week high and low prices for one share of PetroChina Company Ltd is $52.78.
The difference between the day's high and low prices for McDonald's Corporation is $3.40.
The volumes for each of the following stocks are as follows:
a. Berkshire Hathaway Inc: 41,250,000 shares
b. McDonald's Corporation: 2,100,000 shares
c. Texas Instruments Inc: 1,750,000 shares
d. Westpac Banking Corporation: 4,500,000 shares
The closing prices on April 21 for each of the following stocks are:
a. Texas Instruments Inc: $198.64
b. Freeport-McMoran Copper & Gold Inc: $47.92
The percent of net change from April 21 to April 22 for each corporation listed in Exercise 5 is as follows:
a. Texas Instruments Inc: -1.5%
b. Freeport-McMoran Copper & Gold Inc: +2.3%
On April 22, the stock(s) with a daily high approximately 50% lower than the 52-week high is/are not identifiable from the provided information.
If the April net change for Westpac Banking Corporation was -3.03, the closing price for that day was $ 23.97.
Step-by-step explanation:
The difference between the 52-week high and low prices for PetroChina Company Ltd is calculated by subtracting the 52-week low from the 52-week high. In this case, it is $85.53 (52-week high) - $32.75 (52-week low) = $52.78.
To find the difference between the day's high and low prices for McDonald's Corporation, subtract the low from the high: $250.00 (day's high) - $246.60 (day's low) = $3.40.
The volume for each stock is the total number of shares traded. This information is directly provided in the question for each stock.
The closing prices for April 21 are also given directly in the question for Texas Instruments Inc ($198.64) and Freeport-McMoran Copper & Gold Inc ($47.92).
The percent of net change is calculated by taking the difference in closing prices and dividing it by the closing price on April 21, then multiplying by 100 to get a percentage. For Texas Instruments Inc, it is [(closing price on April 22 - closing price on April 21) / closing price on April 21] * 100 = [($195.64 - $198.64) / $198.64] * 100 = -1.5%. For Freeport-McMoran Copper & Gold Inc, it is [(closing price on April 22 - closing price on April 21) / closing price on April 21] * 100 = [($49.00 - $47.92) / $47.92] * 100 = +2.3%.
The information provided doesn't specify which stock(s) had a daily high approximately 50% lower than the 52-week high on April 22.
If the net change for Westpac Banking Corporation was -3.03, it means the closing price on April 21 ($24.75) minus the net change equals the closing price on April 22: $24.75 - (-3.03) = $27.78.
