Neeta plans to invest $20 at the end of every 6 months into an account that pays 17% interest compounded semi-annually. What is
astraxan [27]

The investment value will be $465.15.The amount he invested will be $200.

<h3>What is compound interest?</h3>

Compound interest is computed on a loan or deposit based on the starting principle and the preceding period's accrued interest.

Money invest one time in six months = $20

Interest = 17%

Compounded type = semi-annually

The principal amount invested:

Money invested = $ 20 in 6 month

If he invests for 5 years, in 5 years there are 10 times she invests;

Investment(principal)=$ 20 × 10

Investment(principal)=$ 200

The compound interest:

A= 200(1+\frac{0.17}{2})^2.5 \\\\ A=$ \ 452.2

A =P+CI

452.2=200+CI

CI=252.2

The final balance is $452.2.

The total compound interest is $252.2.

Hence, the investment value will be $452.2.

bixtya [17]

Answer: She is correct that she can use a division expression.

It would be  $4/(2/3)  OR 4 ÷ 2/3 = cost per pound.

Not an easy division, but using the rule: invert the divisor and multiply.

4 × 3/2 = 6  So the cost is $6 per pound.

Step-by-step explanation: It would be easier to answer if the statements were included.

Using a decimal equivalent for 2/3,  4/0.667 is an easy division expression to solve on a calculator.
