Your friend buys a skateboard that is on sale for one third off the original price. Your friend spent $36 than the original pric

White raven [17]

Answer:

original price of skateboard = $54

Step-by-step explanation:

Let the original price of the skateboard be x

selling price = one third off the original price = $36

x - (1/3x) = 36

$\frac{x}{1} - \frac{x}{3} = \frac{3x-x}{3} = \frac{2x}{3}$

$\frac{2x}{3} = 36\\2x = 108\\x = \frac{108}{2} = 54$

∴ x = 54
