For example
1>x>3
says x is less than 1 and greater than 3
C,B,D,A
8/4= 2
4/3= 1 1/3
7/5 = 1 2/5
7/10 cant be simplfied at all
Using the profit concept, it is found that she makes a profit of $4 selling a dozen cookies for six dollars.
<h3>What is a profit?</h3>
The profit is given by the <u>subtraction of the revenue by the total costs</u>.
In this problem:
- For the dozen cookies, she earned a revenue of 6 dollars.
- In all, the total cost of the 12 cookies was of 0.5 + 0.7 + 0.4 + 0.4 = 2 dollars.
6 - 2 = 4, hence she makes a profit of $4.

- Radius of Earth; 6.4 x 100 meters = 640 meters
Clearly, the shape of the earth is a sphere. Thus, to determine the volume of the earth, we will use a formula that determines the volume of a sphere.
When we substitute the radius in the formula, we get;
Take π as 3.14
Simplify the numerator;
Divide the numerator by 3;
