If I am wrong then it could be B. I hope I could help.
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.

Answer:
![x=2\\y=22\\or\\(2,22)](https://tex.z-dn.net/?f=x%3D2%5C%5Cy%3D22%5C%5Cor%5C%5C%282%2C22%29)
Step-by-step explanation:
![x+y=24\\y=11x](https://tex.z-dn.net/?f=x%2By%3D24%5C%5Cy%3D11x)
Subtitute y in the first equation.
![x+y=24\\x+11x=24\\12x=24\\x=\frac{24}{12}\\ x=2](https://tex.z-dn.net/?f=x%2By%3D24%5C%5Cx%2B11x%3D24%5C%5C12x%3D24%5C%5Cx%3D%5Cfrac%7B24%7D%7B12%7D%5C%5C%20x%3D2)
Now replace x in either equation to find y.
![y=11x\\y=11(2)\\y=22](https://tex.z-dn.net/?f=y%3D11x%5C%5Cy%3D11%282%29%5C%5Cy%3D22)
