During a sale, a shop allows 20% discount off the marked price of clothing. What will a customer pay for a dress with a marked price of $30? * 1 point

Answers

Answer:

$24

Step-by-step explanation:

Let the full price of $30 be 100%.

If the discount allowed is 20%, then the percentage of the original price that a customer will pay is:

$P=100\%-20\%\nP=80\%$

80% of a marked price of $30 is:

$80\%*\$30\n\$24$

A customer will pay $24.

They will pay 24 dollars
