Suppose you take out a loan for $9,000, at 12% ordinary interest. If the amount of interest is $762.00, what is the time period?

Ierofanga [76]

Answer:

answer is option c

Step-by-step explanation:

Amount = $9,000

interest rate (r) = 12%

interest = $762.00

time = ?

we know,

$I = \dfrac{PRT}{100}$

$762 = \dfrac {9000\times 12\times T}{100}$

t = 0.7056 years

t = 0.7056 × 365 days

t = 257.54 days ≅ 258 days

correct answer is option c.

The area of the house is the amount of space on the house.

The length of the addition is x + 20
The area of the original house is $x^2 + 30x + 200$

<h3>The length of the addition</h3>

The area of the addition is given as:

$Area = x^2 + 10x - 200$

Expand

$Area = x^2 + 20x - 10x - 200$

Factorize

$Area = x(x + 20) - 10(x + 20)$

Factor out x + 20

$Area = (x -10)(x + 20)$

The width of the addition is x - 10.

Hence, the length of the addition is x + 20

<h3>The area of the original house</h3>

The dimension of the original house is

x + 20 by x + 10

So, the area is:

$Area =(x + 20)(x + 10)$

Expand

$Area =x^2 + 20x + 10x + 200$

This gives

$Area =x^2 + 30x + 200$

Hence, the area of the original house is $x^2 + 30x + 200$
