- x = 13, -6
Answer: 20%
Step-by-step explanation:
To find the total number of problems Emilia solved, we can first add 19 and 76 to get:
19 + 76 = 95
Next, to find how many problems Emilia got correct out of the total, we can use the number of problems correct (19) and divide it by the total number of problems (95) to get:
19 ÷ 95 = 0.2
Finally, to make 0.2 a percentage, we can multiply it by 100 to get:
0.2 X 100 = 20
Therefore, Emilia got 20% of the problems correct.
Answer: Company B
Step-by-step explanation:
First we must calculate the area of the carpet. Variable A represents area.


So the area of the carpet is 168 square feet.
To find what company A will charge we will multiply the 168 by 2.75 they charge per square foot.

Company A charges, $462, while Company B will charge $450 for the one room.
This means Company B has the better price.
