$11.9

Step-by-step explanation:

We are given;

The cost of the cell phone is $170

Tax rate is 7%

We are required to find how much tax is paid on the cell phone.

The tax rate is 7% of the cost of the cell phone

That is;

7% of $170

also; 7/100 of $170

Thus, tax paid = 7/100 × $170

                        = $11.9

Thus, the tax paid on the cell phone is $11.9
