Sarah deposits $4,000 at the bank at an rate of 4.5% per year. How much interest will she earn at the end of 3 years?

Sarah will earn $540 interest at the end of three years.

How to:

- In this problem, we must find the simple interest in order to solve. First let's write the formula for simple interest.

Simple Interests = Principal × Interest Rates × Time

- Now, we will determine what is the value of the each.

The 'principal' is $4,000 [amount of money deposited].

The 'interest rates' is 4.5% [percent of the principal earned].

The 'time' is 3 [length of time].

- Finally, we will plug in the values and solve.

Simple Interests = $4,000 × 4.5% × 3

Simple Interests = $540.00

So... Sarah will earn $540 interest at the end of 3 years.

And that is our answer!

Hope this helps!

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
