Answer:
The correct answer is total revenue; total cost.
Explanation:
Cost reduction is one of the most addressed issues in companies. They do it all the time since it is a permanent process. This is because it always seeks to improve the profitability of the company and, consequently, productivity. In other words, try to "do more with less", which is to produce more with what you have or produce the same with lower expenses. In both cases the objective is to reduce costs.
A company can reduce costs for many reasons: for a drop in sales, for lack of liquidity, for not having access to credit, etc. And when this happens, the cost cut occurs in the areas of human resources with the dismissal of personnel, the restructuring of the purchase processes, changes of suppliers, among other measures.
It is important to know what the current production process is and, if possible, redesign it, seeking to eliminate unnecessary steps, that is, to shorten the production processes. A long production line implies a greater number of workers, more work in the process and more time in product development. It also increases the possibility of errors in the process.
To make the cost reduction in your company even more efficient, you need to know each process deeply to detect unnecessary steps and help you reduce processes and / or procedures that in the medium or long term translate into cost reduction.
Answer:
a. $28.5
b. 12.28%
c. $29.18
d. 13.09%
Explanation:
a. let current price = p
p*1.10 = 2(1-0.3)+30
= 1.4+30/1.10
= 31.4/1.10
= 28.5
the current price of the stock is approximately 28.5 dollars
b. (30+2 /28.5)-1
= 32/28.5 - 1
= 0.1228
= 12.28%
expected before tax rate is 12.28%
c. 3(1-0.3)+30 / 1.10
= 3*0.7+30/1.10
= $29.18
d. before tax rate of return
= (3$ + 30-29.18)/29.18
= 0.1309
= 13.09%
it is now higher here given that given that a greater dividend causes more tax burden.
