the skate shop owner wants 30 percent of each order to include longboards. he wants to know how many longboards to order out of 50 skateboards

15

Explanation:

The question is essentially asking 30% of 50.

to get 30 percent you first need to find out 10 percent.

10 percent is calculated by dividing 50 by 10, giving you 5.

you then need to get 30 percent from the 10 percent just calculated.

to do so, you need to times 10 percent by 3, therefore have to time 5 buy 3, leaving you with 15

Answer:30% if 100
