Calculate the following scenario for a simple interest loan.

Semenov [28]

Simple interest is a method of calculating interest on an amount for n period of time with a rate of interest of r. The amount of monthly payments is $287.5.

<h3>What is simple interest?</h3>

Simple interest is a method of calculating interest on an amount for n period of time with a rate of interest of r. It is calculated with the help of the formula,

SI = (PRT)/100

where SI is the simple interest, P is the principal amount, R is the rate of interest, and T is the time period.

Given the following details about the simple interest loan as,

Principal amount, P = $3,000

Interest rate, r = 15%

Number of instalments = 12

Since there are 12 instalments each for a month, therefore, the time period for which the loan was there is 1 year.

Now, the interest for 1 year will be,

Interest amount = ($3,000 × 1 × 15)/100

= $450

Further, the total amount that is needed to be paid back is the sum of the principal amount and Interest amount.

Amount needed = $3,000 + $450

= $3,450

Moreover, there are 12 instalments, therefore, the number of monthly payments will be,

Monthly payment = $3,450/12 = $287.5

Hence, the amount of monthly payments is $287.5.

The size of a typical city park is about 5 acres, or 217,800 square feet. If a developer plans to

pshichka [43]

Using the percentage concept, it is found that 95.4% of the park will be used for other activities.

<h3>What is a percentage?</h3>

The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:

$P = \frac{a}{b} \times 100\%$

In this problem, there will be two courts of 5,000 square feet each, totaling 10,000 square feet. The remainder 207,800 square feet will be used for other activities, hence the percentage is given by:

$P = \frac{207,800}{217,800} \times 100\% = 95.4\%$

95.4% of the park will be used for other activities.

valkas [14]

Answer:

About $118.70

Step-by-step explanation:

139 x .2 = 27.8

139 - 27.8 = 111.2

111.2 x .0675 = 7.5

111.2 + 7.5 = 118.7

118.7 = $118.70

Complete the equation of the line through (4,-8)(4,−8)left parenthesis, 4, comma, minu

In-s [12.5K]

Equation of a line is in the form y = mx+c, where m is the gradient and c is the y-intercept.

First step is to find the gradient.

m = (y2-y1)/(x2-x1)
= ( 5- -8)/(8-4) = 13/4

We have y = (13/4)x + c

Now we replace one of the coordinates to find c. Let’s replace (4,-8)

We have: -8 = (13/4)*4 + c

-8=13+c
c=-8-13= -21

Therefore, equation of line is:

y = (13/4)x - 21
