The original price of a bike is $129. the sale price is 80% off the original price. what is the sale price if the bicycle

$129 x .80 = $103.20 (80% discount)

$129 (original price) - $103.20 ( 80% discounted amount) = $25.80 (sale price)

The sale price is $25.80

You want to buy something that costs $129, and it's on sale for 80% off. What is the item's sale price?

First, convert the 80% to a real mathematical number. For percent's, this is always done by dividing the 80% by 100%, or 80% / 100%    =    0.800.

Second, find out what 80% of $129 is. This is the amount of the sale discount. This is always found by multiplying 0.800 by the item's cost $129, like this:  

0.800  x    $129     =     $103.20.

So for this sale, you'll save $103.20 on this item.

This means, the cost of the item to you is

$129   -    $103.20     =   $25.80.

Before Price:    $129.00

Discount %:      80%

Answer  >   Sale Price:    $25.80 would be the sale price of the bicycle.

Amount Saved:    $103.20

Alternatively, you can think about it this way.

The item is 80% off. This means you'll pay 20.000% of the total cost (100%     -     80%     =     20.000%).

Now what's 20.000% of the total cost?  

0.200 x $129   =   $25.80.

Just like the result above, the sale price on the item is $25.80.

Hope that helps                                      : )

2,600 divided by 80 = 32.5
