What is 25% Of 30% Of 400?
marta [7]

Answer:

25% of 30% of 400 = 30

33% decrease in value

Step-by-step explanation:

You can either get 30% of 400 first then 25% of 400 or you can get the total percentage of 400.

Method 1:

30% of 400 = 0.3 of 400 = 0.3 * 400 = 120

25% of 120 = .25 of 120 = .25 * 120 = 30

Method 2:

30% of 25% = 0.3 * 0.25 = 0.075 = 7.5% of 400

7.5% of 400 = 0.075 of 400 = 0.075 * 400 = 30

5.) To find the percentage  of the new price, you can build the equation below.

\frac{new price}{original price} = \frac{percent}{100}

\frac{200,000}{300,000}  = \frac{x}{100}

20,000,000 = 300,000x

x = 66.667

The percentage decrease in price is then 100% of the original price - 66.667% of the original price = 100% - 66.67% = 33.33% = 33% decrease.

I NEED NUMBER 24 ONLY PLEASEEEEEEEEEEEE I NEED HELP I DON’T GET IT!!!!!!
siniylev [52]

Answer:

$325,120.00

Step-by-step explanation:

This is my first answer so hopefully I do this correctly. In essence it's exactly the same as number 22!

The realtor earns $10,566.40 off of a comission of 3.25%. A comission is pretty much just a cut of however much the house cost; which a realtor gets for helping to sell the property. So we could say that the comission is equal to 3.25% of however much the house cost.

Say the house price = $x, so our equation would be:

$10,566.40 = (3.25%)•($x) or

10,566.40 = (.0325)•($x)

By solving for x we get:

$x = (10,566.40)÷(.0325) = $325,120

Anni [7]

Answer:

18in

Step-by-step explanation:

Given data

Height h= 15 in

Area= 135 in^2

The expression for the area is given as

Area= 1/2 Base * Height

substitute

135= 1/2* Base*15

135= 7.5 Base

Base= 135/7.5

Base=  18 in

Hence the base is 18in
