Brick = 3.5 in by 7.5 in and costs $0.59
Paver = 8.4 in by 8.4 in and costs $1.88
The small patio's area = 3430 square inches
The Area of 1 Brick = 26.25 square inches
The Area of 1 Paver = 70.56 square inches
The # of Bricks to complete the Patio will be:
Patio's Area / the Area of 1 Brick = # of Bricks to complete the patio
3430 square inches / 26.25 square inches = 130.67 = 131
Then, multiply the # of Bricks to complete the patio by the amount that 1 brick costs:
131 * $0.59 = $77.29
It will take $77.29 to complete the Patio with bricks.
The # of Pavers to complete the Patio:
Patio's Area / the Area of 1 Paver = # of Pavers to complete the Patio
3430 square inches / 70.56 square inches = 48.6 = 49
Then, multiply the # of Pavers to complete the patio by the amount that 1 Paver costs:
49 * $1.88 = $92.12
Cost of Bricks to complete Patio = $77.29
Cost of Pavers to complete Patio = $92.12
To conclude, Bricks would cost less by $14.83.
Here is a simple way we can do this.
We have six blanks.
__ __ __ __ __ __
Now, we have 13 possible options to fill in blank number one.
13 __ __ __ __ __
Now we have 12 possible options to fill in blank number two because one person has already been chosen.
13 12 __ __ __ __
Now we have 11 possible options for blank number three.
13 12 11 __ __ __
Now we have 10 possible options for blank number four.
13 12 11 10 __ __
And so forth until we get:
13 12 11 10 9 8
Now we just have to multiply the numbers all together.
13 * 12 * 11 * 10 * 9 * 8
is equal to:

Step-by-step explanation:
If u have a open circle, then the inequality has no equal sign. But if it is a closed circle, the inequality has an equal sign.
Shading to the left means " less then " .
Shading to the right means " greater then " .
(1) u have an open circle on -7 with shading to the left....
x < -7
(2) u have a closed circle on 4.5 with shading to the left....
x < = 4.5 (thats less then or equal)
(3) u have an open circle on -5 with shading to the right...
x > -5
(4) u have an open circle on 1.5 with shading to the right...
x > 1.5
