## How to figure out a 30 percent discount on 42.5 - Step-by-Step

Problem: Calculate the exact sale price of an item originally priced at \$42.50 and now has a 0.30% discount. See, below, how to solve it in three steps.

### Step 1 - Convert the percentage discount to a decimal

Imagine the percent number with a decimal to the right of the last digit, then, move the decimal point two places to the left.

30% = 30.00% = 0.30

### Step 2 - Multiply the price before the discount by the decimal

You will find the discount, or what value is being taken off the price before the discount. You can use a calculator to do it.

42.50 × 0.30 = 12.75 (discount)

### Step 3 - Subtract the discount from the price before the discount

Subtracting the discount from the price before the discount will give you the sale price of the item. So,
