Jim started with b baseball cards and gave 13 away. So, that means we take away from his starting amount or b.

So, b - 13 is the expression you are looking for.

Find the balance of $7,000 deposited at 4% compounded semi-annually for 2 years

Rufina [12.5K]

Answer:

The balance will be $7,577.03.

Step-by-step explanation:

The compound interest formula is given by:

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

Where A is the amount of money, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per unit t and t is the time the money is invested or borrowed for.

In this problem, we have that:

$P = 7000, r = 0.04$

Semianually means twice a year, so $n = 2$

We want to find A when $t = 2$ .

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

$A = 7000(1 + \frac{0.04}{2})^{2*2}$

$A = 7577.03$

The balance will be $7,577.03.
