The simple interest (I) is calculated by multiplying the principal amount (P) with the interest rate (R) and time (T) or expressed in formula as Simple Interest = Principal x Interest Rate x Time or I = P × R × T.

Simple interest is a method of calculating the interest on a loan or investment in which the interest is based only on the original principal (initial amount invested or borrowed) that is multiplied by the interest rate and the duration of time in years. The formula for calculating simple interest is:

Simple Interest = (Principal x Interest Rate x Time)

For example, if you borrow $1,000 at a simple interest rate of 5% per year (0.05 in decimal) for 2 years, the interest would be:

Simple interest = 1000 x 0.05 x 2

The ordered pair (2,1) is a solution of the system of linear equations.

To determine whether the ordered pair (x, y) is a solution of the system of linear equations:

6x - 3y = 18

2xy = 7

We can substitute the values of x and y from the ordered pair into the equations and see if they make the equations true.

For example, if the ordered pair is (2,1) we can substitute these values into the equations:

6(2) - 3(1) = 18

2(2)(1) = 7

If both equations are true, then the ordered pair is a solution of the system of linear equations. If either equation is false, then the ordered pair is not a solution of the system of linear equations.

In this case,

6(2) - 3(1) = 18 is true

2(2)(1) = 7 is true

So, the ordered pair (2,1) is a solution of the system of linear equations.

 A project with an initial cost of $65,550 and projected annual cash flows of $17,900 has an internal rate of return of 16.23%.

Internal rate of return or known as IRR is a project evaluation method to measure a project's profitability based on the time value of money concept. IRR refers to a discount rate of a project that could make its net present value (NPV) equals to zero (0).

IRR can be calculated through the same approach with NPV. IRR can be calculated using NPV formula:

NPV = T∑(t=1) [tex]\frac{Ct}{(1+IRR)^t} - C_{0}[/tex] = 0

where:

Ct = net cash inflow during the t period

IRR = Internal rate of return

C0 = initial investment

t = time of period

From the case, we know that:

C0 = $65,550

Ct = $17,900

t = 6 years

IRR = ?

Using the NPV formula, the IRR to make NPV of the project equals to 0 (zero) is:

NPV = T∑(t=1) [tex]\frac{Ct}{(1+IRR)^t} - C_{0}[/tex] = 0

0 = T∑(t=1) [tex]\frac{17,990}{(1+IRR)^6}-65,550[/tex]

IRR = 16,23%
