Answer: he should invest $16129 today.

Step-by-step explanation:

Let $P represent the initial amount that should be invested today. It means that principal,

P = $P

It would be compounded annually. This means that it would be compounded once in a year. So

n = 1

The rate at which the principal would be compounded is 7.6%. So

r = 7.6/100 = 0.076

The duration of the investment would be 6 years. So

t = 6

The formula for compound interest is

A = P(1+r/n)^nt

A = total amount in the account at the end of t years.

A = 25000

Therefore

25000 = P(1+0.076/1)^1×6

25000 = P(1.076)^6

25000 = 1.55P

P = 25000/1.55

P = $16129

Passing through(-1,8) and parallel to the line whose equation is 8x-9y-2=0
notka56 [123]
<h3>Answer:</h3>

y = 8/9x + 80/9

<h3>Step-by-step explanation:</h3>

<u>We are given;</u>

  • Equation of a line as 8x -9y -2 = 0
  • Coordinates (-1,8)

We are required to determine the equation of a line parallel to the given line and passing through a point (-1,8)

<h3>Step 1: Determine the Gradient of the given line </h3>
  • When an equation is written in the form y = mx + c, m is the gradient.
  • Therefore; we could write the equation 8x -9y -2 = 0 in the form of  y= mx + c

9y = 8x -2

y = 8/9x - 2/9

Therefore, the slope, m = 8/9

<h3>Step 2: Determine the equation of the line</h3>
  • We need to know that parallel lines have the same gradient
  • Therefore, the slope of the line in question is 8/9
  • It passes through a point (-1, 8)

We can therefore, determine the equation;

Taking another point, (x,y)

\frac{y-8}{x+1} = \frac{8}{9}

9(y-8) = 8(x+1)

9y - 72 = 8x + 8

 9y = 8x + 8 +72

 9y = 8x + 80

  y = 8/9x + 80/9

Therefore, the equation of the line is y = 8/9x + 80/9

John Smith made a one year investment that generated a nominal return of 6% or $3000. The real return was $2000. What was the or
nata0808 [166]

The nominal value - without discounting the inflation rate - of income was $ 3000.

If the interest rate was 6%, a rule of three is enough to find the value of the original investment.

3000 - 6%

x - 100%

x = 50,000

The value of the investment was $ 50,000

In this case, the inflation rate also requires a simple calculation.

Inflation corroded $ 1000 dollars of income of $ 3000

Therefore the inflation rate will be 1000/3000 = 33.3%
