Yes, it is an equivalent expression because even though you move two pieces of an equation it will still equal the same thing, unless there are parentheses involved.
Answer:the answer to this will be 14m
The sales tax rate would be 8%.
To find how much you spent on tax in the total, you'd begin by subtracting the pre-tax notebook from the after tax notebook.
4.86 - 4.50 = 0.36
So now we know that you spent 36 cents on tax. From there, we'd divide our money spent on tax by our pre-tax total.
0.36 ÷ 4.50 = 0.08
This means that the sales tax is 8%.
Hope I could help!
