Answer:
He should order 15 long boards
Question:
Escape park owner want 30% of each order to include long boards he wants to know how many long boards to order out of a total of 50 skateboards
Explanation:
Let x and y represent the number of long board and the total number of skateboard to order.
Given that 30% of each order to include long boards;
x = 30% of y
x = 0.3y .....1
But, the total number of skateboard is given as 50
y = 50
From equation 1
x = 0.3y = 0.3(50)
x = 15
He should order 15 long boards
