Answer: 5.70
Explanation:
Gift card = 25
Canvases = x
Since Andrea is buying four canvases, we can say that it is 4x.
Remaining balance = 2.20
Let's set up our equation. To set it up, we can write it like this
4x+2.20= 25
Now, subtract 2.20 on each side
4x = 22.8
Now divide, and you get around 5.70
So, each canvas was $5.70
