Answer:
ROA = 6.6%
ROE 14.52%
Explanation:
profit margin = net income / sale = 12%
assets turn over = sales / assets = 0.55
equity mutiplier = assets / equity = 2.2
ROE = return on equity = net income / equity
ROA = return on equity = net income / assets
we use the fraction properties to get ROE and ROA

ROA = 6.6%
We apply the same property to get ROE

ROE = 14.52%
Answer and Explanation:
Given that Bond A pays $4,000 in 14 years and Bond B pays $4,000 in 28 years, and that the interest rate is 5 percent, we see that Using the rule of 70, the value of Bond A is 70/5 = doubled after 14 years. Now if its value is 4000 in 14 years, its current value must be halved. Hence the value is 2000.
Sinilarly the value of Bond B is approximately one fourth now because it pays 4000 in 28 years. Hence its value is 4000/4 = 1000.
Now suppose the interest rate increases to 10 percent. Hence the doubling time is 70/10 = 7 years
Using the rule of 70, the value of Bond A is now approximately 1,000 and the value of Bond B is 250
Comparing each bond’s value at 5 percent versus 10 percent, Bond A’s value decreases by a smaller percentage than Bond B’s value.
The value of a bond falls when the interest rate increases, and bonds with a longer time to maturity are more sensitive to changes in the interest rate.
could you explain some more please
Answer:
The answer is below
Explanation:
i) The price elasticity of demand is given by the formula:

Since the price elasticity of demand is greater than 1 hence it is elastic
ii) Since the price elasticity of demand is elastic as a result of increase in fare, hence the total revenue would decrease.
iii)

Since the price elasticity of demand is greater than 1 hence it is elastic
