#### Explanation:

The discount amount $\left(x\right)$ can be calculated as:

$x = 12.25 \times \frac{60}{100}$

$x = 12.25 \times \frac{6 \cancel{0}}{10 \cancel{0}}$

$x = 12.25 \times \frac{6}{10}$

$x = \frac{73.50}{10}$

$x = 7.35$

Since the original price is $12.25, the sales price will be: $12.25 - 7.35 = 4.90\$
