The candy store is having 30% off sell. Emma is going to buy $7.50 worth of candy. How much will she pay after the discount

Emma will pay $5.25

Step-by-step explanation:

In order to find this, we first need to find the amount of the discount. We can do that by taking the overall amount and multiplying it by the percentage decrease.

$7.50 * 30% = $2.25

Now since we know the size of the discount, we can subtract it from the original cost.

$7.50 - $2.25 = $5.25
