A manufacture of skateboards offered a 5/2/1 chain discount too many customers. Bobs sporting goods ordered 20 skateboards for a total of $625 list price. What was the net price of the skateboards?

A discount string 5/2/1 means the following:

1) Apply 5% discount to the original price.

2) Apply 2% discount to the result of step 1).

3) Apply 1% discount to the result of step 2).

We have then that the result will be given by:

625 * (0.95) * (0.98) * (0.99) = 576.05625 $

Then, the price of each skateboard is:

(576.05625) / 20=28.8028125 $

Answer:

The net price of the skateboards was:

28.8028125 $
