Acme Company has variable costs equal to 30% of sales. The company is considering a proposal that will increase sales by $12,000
mina [271]

Answer:

$0

Explanation:

The net income is the difference between the sales and total cost which comprises of the variable cost and fixed cost. The sales and variable cost are dependent on the number of units sold.

Let

u = number of units

s = selling price per unit

v = variable cost per unit

F = Fixed cost

I = Net income

I = su - F - vu

but vu = 0.3su

Hence

I = su - 0.3su - F = 0.7su - F

Given that the proposal will increase sales by $12,000,

New sales = su + 12000          ( in $)

and total fixed costs by $8,400

New fixed cost = F + 8400

New variable cost = 0.3( su + 12000) = 0.3su + 3600

New net income = su + 12000 - 0.3su - 3600 - F - 8400

= 0.7su - F

New net income is same as the old net income hence no increase.

"If the option will cost the investor an additional $10,000, should the investor purchase the option? Enter your answer in thous
kykrilka [37]

Answer:

“Should” or “should not” depend on the cost rate of the option and the risk appetite of investors.

Explanation:

An option is a contract that allows investors to buy or sell instruments such as security, Exchanged Traded Fund or an index at a pre-determined price over a certain period of time.

If the option will cost the investor an additional $10,000 and it is the cost for an option of $10 million investment, then it cost only 0.1% additionally, but it can secure the position of this investment; then the investor should buy this option.

Vice versa, if the additional $10,000 is much more than expected profit, and even lower but significantly drop down the total profit of an investment; and the investor always wish to have a high profit regardless high risk; then he shouldn’t buy this option.
