Question

the price of a tv was originally 374.99 and reduced to 299.50. what was the percent decrease of the price of the tv round your answer to the nearest tenth

Answer 1

first you should say: 
374.99 - 299.50 = 75.49
so now you should say:
75.49/374.99 = ?/100
so ? is the percent:
? = (75.49*100)/374.99 = 20.131 % :)))
i hope this is helpful
have a nice day
