Introduction

When shopping for a portable table tennis set, it's essential to consider the cost and any potential discounts that may be available. In this scenario, a portable table tennis set costs $\$30$ before a $30\%$ discount. The goal is to find the sale price of the set after the discount has been applied.

Understanding Discounts

A discount is a reduction in the original price of an item. In this case, the portable table tennis set has a $30\%$ discount, which means that the price will be reduced by $30\%$ of the original price. To find the sale price, we need to calculate the amount of the discount and subtract it from the original price.

Calculating the Discount

To calculate the discount, we need to find $30\%$ of the original price of $\$30$. We can do this by multiplying the original price by the discount percentage.

$$\text{Discount} = \text{Original Price} \times \text{Discount Percentage}$$

$$\text{Discount} = \$30 \times 0.30$$

$$\text{Discount} = \$9$$

Finding the Sale Price

Now that we have calculated the discount, we can find the sale price by subtracting the discount from the original price.

$$\text{Sale Price} = \text{Original Price} - \text{Discount}$$

$$\text{Sale Price} = \$30 - \$9$$

$$\text{Sale Price} = \$21$$

Conclusion

In conclusion, the sale price of the portable table tennis set after a $30\%$ discount is $\$21$. This is the price that the customer will pay for the set after the discount has been applied.
