Identify the base in the following application: The sales tax rate is 8%. If you pay a tax of $2.50 on an item, what is the selling price. I don't know what the base is or how to solve the problem.

Check your text to find how base is defined in this situation.

To find the marked price before the tax, solve for x.

0.08x = 2.5

x = 2.5/0.08

x = 31.25

In the problem is the base "unknown"?
