In most cases for this type of questions you would have to use a calculator, since this is not a value that can be approximated. Do you have an inverse normal function on your graphical calculator?

An investment will pay $100 at the end of each of the next 3 years, $200 at the end of Year 4, $300 at the end of Year 5, and $6
Tomtit [17]

Answer:

present value $ 1,026.16

future value  $ 1,539.98

Explanation:

Present Value = $ 100 * 1/(1.07) ^ 1 + $ 100 * 1/(1.07) ^ 2 +$ 100 * 1/(1.07) ^3 + $ 200 * 1/(1.07) ^4 + $ 300 * 1/(1.07) ^5 +$ 600 * 1/(1.07) ^6

=93.45+ 87.34+81.62+152.20+213.23+398.32

= $ 1,026.16

therefore,  the correct value  is $ 1,026.16

b. Future Value = Present Value * ( 1+ Rate of Interest ) ^ Time

= $ 1,175.63 * ( 1+0.07) ^ 6

= $ 1,539.98

Hence the correct answer is $ 1,539.98

What is the typical relationship between time and interest rate everfi?
klasskru [66]
<span>Interest rate is directly proportional to time. An interest rate is the amount of money due per period or a proportion of the amount borrowed or deposited. The total interest depends on the principal sum and the length of time over which it is lent or deposited. Therefore, the value of money will depend on interest rate and time. The longer time of debt or bank deposit, the higher interest rate.</span>

When comparing absorption costing and variable costing, if units produced are units sold, what is the effect on net operating in
11111nata11111 [884]

Answer:

The Net Operating income will be the same for both methods.

Explanation:

Net Operating income under absorption costing and variable costing methods usually differ because of existence of inventory.

Fixed overheads are deferred in Inventory when using absorption costing. Meaning that a higher income is obtained under absorption costing than variable costing when there is inventory and a lower income under absorption costing than variable costing.

When units produced are units sold, there is no inventory. Therefore, the Net Operating income will be the same for both methods.

Oliga [24]

Answer:

$926,000

Explanation:

For computing the initial cost of the warehouse project, we consider the current value of the land i.e represent the opportunity cost and the land value which is purchased six years ago for $874,500 represent the sunk cost which is not recoverable now. So, this sunk cost is not relevant.

And, the lease cost is also not relevant as the lease period will be ended soon.

All other information which is given is not relevant. Hence, ignored it
