Angelina deposits $3000 in a savings account on 1 January 2019, earning compound interest of 1.5% per year.

jekas [21]

The interest earned would be $481.62.

The total amount of money in her account would be $16,377.12.

<h3>Determining interest after 10 years </h3>

Interest = future value - amount deposited

$3000 (1.015)^10 = $3,481.62

Interest = $3,481.62 - $3000 = $481.62

<h3>Determining the future value of the account.</h3>

Future value of the lump sum = $3000 x (1.015)^11 = $3,533.85

Future value of the annuity = amount deposited x annuity factor

Annuity factor = {[(1+r)^n] - 1} / r = [(1.015)^10 - 1] / 0.015 = 10.702722

Future value = 10.702722 x $1,200 = $12,843.27

Total future value = $12,843.27 + $3,533.85 = $16,377.12

You have decided to invest $1000 in a savings bond that pays 4% interest, compounded semi-annually. What will the bond be worth

Evgen [1.6K]

Answer:

$2191.12

Step-by-step explanation:

We are asked to find the value of a bond after 10 years, if you invest $1000 in a savings bond that pays 4% interest, compounded semi-annually.

$FV=C_0\times (1+r)^n$ , where,

$C_0=\text{Initial amount}$ ,

r = Rate of return in decimal form.

n = Number of periods.

Since interest is compounded semi-annually, so 'n' will be 2 times 10 that is 20.

$4\%=\frac{4}{100}=0.04$

$FV=\$1,000\times (1+0.04)^{20}$

$FV=\$1,000\times (1.04)^{20}$

$FV=\$1,000\times 2.1911231430334194$

$FV=\$2191.1231430334194$

$FV\approx \$2191.12$

Therefore, the bond would be $2191.12 worth in 10 years.

Solve each equation. Explain your method.8.88=4.44(x−7)

omeli [17]

8.88=4.44(x−7)

write the equation

8.88 - 4.44=(x−7)

Transfer 4.44 to other side and it's sign changes from positive to negative

4.44=(x−7)

After subtracting we will get result as 4.44

(x−7) = 4.44

Arrange the equation as variable always comes at left side.

x−7 = 4.44

open brakets

x = 4.44 + 7

transfer 7 to other side and it changes from - to + sign

x = 11.44
