Answer:

Step-by-step explanation:

First of all, the interest is compounded which means that the new principle is the principle from the year before added to the interest from the year before.

So, for example, at the end of the first year she will have accumulated 60 dollars in interest. That 60 dollars is added to the 2000 and the second year will give you 2060 dollars as your principle. That means that anything using 0.03 is incorrect if not with the 1.

A and C are both incorrect.

You don't want to be adding even if you are using 1.03. So that means

D is incorrect.

The answer must be B

If the length of a rectangle is increased by 120%, and its width is decreased by 20%, what is the percentage change in the area

velikii [3]

Answer:

The area of the rectangle is increased in 76 percent.

Step-by-step explanation:

The area of a rectangle ( $A$ ) is represented by the following formula:

$A = w\cdot l$

Where:

$w$ - Width.

$l$ - Length.

If length is increased by 120 %and width is decreased by 20 %, the percentage change in the area of the rectangle is: ( $l = 2.2\cdot l_{o}$ , $w = 0.8\cdot w_{o}$ )
