A ​$240 suit is marked down by ​%30. Find the sale price.

Shadow:

You can find 30% of 240 by multiplying 240 by 0.3. Then subtract the number you get from 240. In an equation this looks like: 240 - 240(0.3)

Shadow:

The suit is $240 and is being marked down by 30% This means that there is a 30% reduction of the current price. So we find 30% of the current price, which is 240. Then subtract that number, 30% of 240, from $240 This gives us our new price of this $240 suit now marked down by 30%

Shadow:

You can find 30% of 240 by multiplying 240 by 0.3 0.3 is the same as 30%

To convert a percent to a decimal, just move the dot two places to the left.
