Answer:
The equation
could be used to represent this situation.
Step-by-step explanation:
Given:
Azul bought 10 reams of paper at the store for a total cost of $84 the tax on the purpose was $4.
Now, to find the equation that could be used to represent this situation.
Let the cost of a ream of paper be ![x.](https://tex.z-dn.net/?f=x.)
Total reams of paper = 10.
The tax on the purpose = $4.
The total cost = $84.
Now, to write an equation to represent this situation:
![10\times x+4=84](https://tex.z-dn.net/?f=10%5Ctimes%20x%2B4%3D84)
![10x+4=84](https://tex.z-dn.net/?f=10x%2B4%3D84)
Therefore, the equation
could be used to represent this situation.
