Answer

Explanation:

Step1: Find the amount of tax paid

The customer paid $1.62$ for an item marked $1.50$. The tax amount $t$ is the difference between the total amount paid and the marked - price. So, $t=1.62 - 1.50=0.12$.

Step2: Calculate the tax rate as a percentage

The tax rate $r$ (as a percentage) is calculated by the formula $r=\frac{t}{p}\times100%$, where $t$ is the tax amount and $p$ is the marked - price. Substitute $t = 0.12$ and $p = 1.50$ into the formula: $r=\frac{0.12}{1.50}\times100%$. First, $\frac{0.12}{1.50}=0.08$. Then, $0.08\times100% = 8%$.

Answer:

$8%$
