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)

Respuesta :

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

[tex]\frac{400}{170}-100\text{\%}=2.3529-1=1.3529=135.29\text{\%}[/tex]

So the percent increase was 135.3%.
