OpenStudy (anonymous):

holy crap, i dont know

hartnn (hartnn):

let the price be 100 units. raised by 20% means its 120 units now. Let it reduce by x% to get back 100 so, \(120-120\times x/100=100\) solve for x

OpenStudy (anonymous):

x=50/3

hartnn (hartnn):

yes, i get the same.....16.67%

OpenStudy (anonymous):
