Emma buys a softball that is 70% off. If the original price is $30, how much does Emma pay?

Korvikt [17]

Answer:

Explanation:

First, we need to find 70% of the original price of $30 using the following equation:

$\text{ \$30 }\times70\text{ \% = \$30 }\times\frac{70}{100}=\text{ \$21}$

It means that Emma pays $21 less than the original price. So, she pays:

$30 - $21 = $9

Therefore, the answer is $9
