Answer:

The future value of annuity is $27850302.48

The Investment amount is $ 37900.259

The compound interest is $ 662799.741

Step-by-step explanation:

Given as :

The due amount = $ 700700

the rate of interest compounded semiannually = 88%

The time period  = 4 years

Let The investment principal = $ P

The interest = CI

Let The future value of annuity = FV

Now, <u>The future value of Annuity method</u>

FV = Amount × \frac{(1+\frac{Rate}{2\times 100})^{2\times time}- 1}{\frac{Rate}{2\times100 }}

Or, FV = $700700  × \frac{(1+\frac{88}{2\times 100})^{2\times 4}- 1}{\frac{88}{2\times100 }}

Or, FV = $700700  ×  \frac{(1.44)^{8}-1}{0.44}

Or, FV = $700700  × 39.7464

∴   FV = $27850302.48

<u>Now, from compounded method</u>

Amount = Principal × (1+\frac{Rate}{2\times 100})^{2\times Time}

Or, $ 700700 =  P  × (1+\frac{88}{2\times 100})^{2\times 4}

Or,  $ 700700 =  P  × (1.44)^{8}

or, $ 700700 =  P  × 18.488

∴ P  = \frac{700700}{18.488} = $ 37900.259

So, Investment amount = $ 37900.259

Now,

Compound Interest = Amount  - Principal

Or, CI = $ 700700 - $ 37900.259

Or, CI = $ 662799.741

Hence The future value of annuity is $27850302.48

The Investment amount is $ 37900.259

The compound interest is $ 662799.741       Answer

What is the value of x in the equation -6x = 5x+ 22?<br> -22<br> 0 -2<br> 02<br> O 22
Ivahew [28]

Answer:

x = -2

Step-by-step explanation:

Solve  -6x = 5x + 22

add 6x to both sides

0 = 6x + 5x + 22

0 = 11x + 22

11x = -22

x = -22/11

x = -2

Nancy bought 3.5 gallons of gasoline. she paid 10.43. What was the price per gallon for the gasoline
schepotkina [342]

Answer:

Nancy paid 2.98 per gallon of gasoline.

Step-by-step explanation:

The price of the gasoline is given by the total amount she paid for the gasoline divided by the amount of gasoline acquired with that money. The calculations for this are shown below:

ratio = total money / total gasoline

ratio = 10.43 / 3.5

ratio = 2.98 money / gallon

Nancy paid 2.98 per gallon of gasoline.

Suppose the population of a certain city is 5289 thousand. It is expected to decrease to 4530 thousand in 50 years. Find the per
Tcecarenko [31]

Answer:

14.4% decrease

Step-by-step explanation:

Here is the formula for finding the percentage of decrease:

(starting value - final value) / starting value * 100.

So for your question,

\frac{5289-4530}{5289} =.0144\\.0144 * 100 = 14.4\\/

There was a 14.4% decrease within 50 years.
