A loan of $100,000 is made today. The borrower will make equal repayments of $3568 per month with the first payment being exactl

Makovka662 [10]

Answer:

The yearly interest rate is 5.20%.

Step-by-step explanation:

This is a compound interest problem

The compound interest formula is given by:

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

In which 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:

The loan outstanding is the value of the loan that has not been repaid.

Here, it is $$25,044.84$ .

To find the interest rate, we first have to find how much money the borrower will have to pay, that will be the value of A in the compound interest formula.

The total he will have to play is $$25,044.84$ plus the $3,568 he has already paid in each of the previous 2 years = 24 months. So:

$A = 25,044.84 + 24*3,568 = 110,676.84$ .

P is the value of loan, so $P = 100,000$

r is the interest rate, the value we have to find.

We have to find the annual interest rate, so $n = 1$ .

We found the total amount in 2 years, so $t = 2$ .

Solving

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

$110,676.84 = 100,000(1 + r)^{2}$

$(1 + r)^{2} = 1.1067684$

To find r, i will take the square root of both sides of the equation. So

$\sqrt{(1 + r)^{2}} = \sqrt{1.1067684}$

$1 + r = 1.0520$

$r = 0.0520$

The yearly interest rate is 5.20%.

Quinton bought x number of shares for p dollars and paid a 0.5% commission. He sold the stock for y dollars and paid a flat fee

Ksju [112]

Answer:

$y-(0.05xp+7)$

Step-by-step explanation:-

As per the statement:

Quinton bought x number of shares for p dollars and paid a 0.5% commission

⇒ $0.05xp$

It is also given that: He sold the stock for y dollars and paid a flat fee of $7.

⇒ $y-7$

then;

Net proceeds is given as:

$y-7-0.05xp = y-(0.05xp+7)$

Therefore, Quinton's net proceeds algebraically is $y-(0.05xp+7)$
