A bicycle that usually sells for 230 is on sale for 15% off. Find the sale price
SSSSS [86.1K]

Answer: $172.50

Step-by-step explanation: Method 1:

The original price of the item is $230.

The discount is 25%.

Let's find 25% of $230.

25% of $230 = 0.25 * $230 = $57.50

The discount amount is $57.50.

Now we subtract the amount of the discount from the original cost.

Sale price = $230 - $57.50 = $172.50

Method 2.

The original price is $230.

That means that $230 is 100% of the price since 100% of a thing means the entire thing.

Since the discount is 25% of the price, we subtract 25% from 100%, 100% - 25% = 75%.

The sale price is 75% of the original price.

Now we find 75% of $230.

75% of $230 = 0.75 * $230 = $172.50
