Answer:
A) The percentage of tax paid by Karen on the Laptop is 2%
Explanation:
The selling price of the laptop = $1800
The tax amount on laptop = $36
Let us assume the tax paid on the laptop = m %
⇒ m% of the selling price = Tax Amount
or, m % of $1800 = $36
![\implies (m)/(100) * 1800 = 36\\or, m = (36 * 100)/(1800) = 2](https://img.qammunity.org/2020/formulas/mathematics/middle-school/rc4b94zyfvbqslv1bpuvpdvx27wrbc8x3w.png)
⇒ m = 2 %
or 2 % of $1800 = $36
Hence, the percentage of tax paid by Karen on the Laptop is 2%
