Trava [24]

Answer:

I invested $ 10,000 at 7% per year, and $ 1,000 at 3% per year.

Step-by-step explanation:

Given that I invested $ 11,000 in two accounts paying 3% and 7% annual interest, respectively, if the total interest earned for the year was $ 730, to determine how much was invested at each rate, the following calculation must be performed:

5,000 x 0.07 + 6,000 x 0.03 = 530

8,000 x 0.07 + 3,000 x 0.03 = 650

10,000 x 0.07 + 1,000 x 0.03 = 730

Therefore, I invested $ 10,000 at 7% per year, and $ 1,000 at 3% per year.

A student is trying to solve the system of two equations given below: Equation P: a + b = 6 Equation Q: 4a + 2b = 19 Which of th
Marrrta [24]

Answer:

-4(a + b = 6)

Step-by-step explanation:

Given

a + b = 6

4a + 2b = 19

Required

Eliminate a

Multiply the first equation by -4

-4(a + b = 6)

Add to the second equation

-4(a + b = 6) + (4a + 2b = 19)

Solve brackets

(-4a -4b = -24) + (4a + 2b = 19)

Open bracket

-4a + 4a -4b  + 2b = -24 + 19

-4b  + 2b = -24 + 19

At this point, a has been eliminated;

From the list of given options, the option that answers the question is -4(a + b = 6)

an initial investment of $480 earns interezt for 7 years in an account that earns 13% interest, compounded quarterly. Find the a
Travka [436]

Answer:

$1,175.34

Step-by-step explanation:

To solve for the total amount after 7 years. We need to use the formula:

A = P(1+\dfrac{r}{n})^{nt}

Let's first break down all the variables that we have.

P = 480

r = 13% or 0.13

n = 4 (Quarterly)

t = 7 years

Now we simply substitute the values into the formula.

A = P(1+\dfrac{r}{n})^{nt}

A = 480(1+\dfrac{0.13}{4})^{4(7)}

A = 480(1+\dfrac{0.13}{4})^{28}

A = 480(1+0.0325)^{28}

A = 480(1.0325)^{28}

A = 480(2.45)

A = $1,175.34

The account will have $1,175.34 after the 7 year period.
