Question

A pair of Air Jordan 1 Retro High OG'University Blue' were originally priced at $170. However, once they soldout, resale price became $400. What is the percent increase for the pair of Air Jordans? (Round to the nearesttenth)

Answer 1

In order to calculate the percent increase, let's divide the new price by the old price and then subtract 100%:

$\frac{400}{170}-100\text{\%}=2.3529-1=1.3529=135.29\text{\%}$

So the percent increase was 135.3%.
