Decide if each answer will be less than or greater than the original number. Drag each to the correct category
enot [183]

That's a question about percentage.

Let's imagine that we want to know how much is 90% of 200. To do this calculation, we should multiply 200 by 90 and then divide the result by 100. We do that because 90% is the same thing that \frac{90}{100} =0,9. So, 90% of 200 is equal to:

\frac{200\cdot90}{100} =\\\\\frac{18000}{100} =\\\\180

Now, imagine that you would like to know how much is 100% of 999. First, we multiply 999 by 100 and divide the result by 999. So, 100% of a number is equal to itself. That's a very important information, because it's possible to understand this:

  • If the percentage is less than 100%, the result is less than original number.
  • If the percentage is equal to 100%, the result is equal to the original number.
  • If the percentage is greater than 100%, the result is greater than original number.

Now, we can solve our problem! \o/

The options that the percentage is less than 100% are: 35% of 300, 62% of 182 and 89% of 525. Therefore, their answers will be less than the original number.

And, the option that the percentage is greater than 100% are: 250% of 18, 300% of 250 and 120% of 72. So, their answers will be greater than the original number.

On the image, you can see the answer in a table.

I hope I've helped. ^^

Enjoy your studies! \o/

Kenya Kon sells dishwashers. He earns an 8% commission on sales. How much must be sell in order to earn $3000?
Karolina [17]
Use a variable to solve for this.

x * .08 = 3000

Divide by .08 on both sides.
x = 37500

We can check this by inputting 37500 for x.

37500 * .08 = 3000
3000 = 3000

Kenya Kon must earn $37500 to earn $3000.

(x) = x + 0.14x, then find the value of T(290).<br> A. 300.45<br> B. 351.2<br> C. 325.8<br> D. 330.6
Katarina [22]

The value of T(290) will be 330.6.The relation between them is shown as T(x)  is dependent and x is the independent variable. Option D s correct.

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

A connection between independent variables and the dependent variable is defined by the function.

Functions help to represent graphs and equations. A function is represented by the two variables one is dependent and another one is an independent function.

Given relation;

T(x) = x +0.14x

Substitute the value of x we get;

T(290) = 290 +0.14×290

T(290) = 330.6

Hence, option D s correct.
