A cell phone costs $170 and has a tax rate of 7%. Write and Solve a proportion to find how much tax is paid on the cell phone.
Darina [25.2K]

Answer:

The Amount of tax paid on the cell phone is $11.9

Step-by-step explanation:

Given as :

The cost of the cell phone = x = $170

The tax rate of the cell phone = r = 7% of the phone cost

Let The Amount of tax paid on the cell phone = $y

<u>Now, According to question</u>

The Amount of tax paid on the cell phone = 7 % of cost of the cell phone

i.e y = 7% of x

Or, y = \dfrac{7}{100} × x

Or,  y = \dfrac{7}{100} × $170

Or, y = \frac{7\times 170}{100}

∴ y = 7 × 1.7

i.e y = $11.9

So,The Amount of tax paid on the cell phone = y = $11.9

Hence, The Amount of tax paid on the cell phone is $11.9   Answer
