Let's look at something. If we had a rectangular solid that has dimensions of 1,1, and 2, the volume would be 2. If we doubled the dimensions to 2,2, and 4, it would be 16. That is 8 times the size of the initial solid.
If we take this and apply it on this solid, the volume would be 256. 
Let's say the dimensions are 2,2, and 8. If we double it, it would be 4,4, and 16, the volume would be 256.

So, the volume would be 256 units³.

Nikita invests $2,000 into a bank account with a 4% annual interest rate. In seven years, which is the most expensive item she c
Stella [2.4K]

Answer:

Anything that does not cost more than $2,560.00

Step-by-step explanation:

Provided that Nikita is spending money that she had invested and the amount  she collected over the period of 7 years. She can buy any item that costs no more than $2,560.00 but how?

It is a problem of simple interest:

Here the principal amount (P) = $2,000.00

Interest rate (r) = 4%

Time period (t) = 7 years

So, total amount that she would get by the end of 7 years is:

A=P+SI

SI=\frac{P\times r\times t}{100}

Plugging the values we get:

SI=\frac{2000\times 4\times 7}{100}=560.00

So the interest collected over 7 years is $560.00

Therefore, the total amount after 7 years is:

\$2000.00+\$560.00=\$2,560.00

If Nikita is using this money then the most expensive item that she could buy will cost no more than $2,560.00.
