## Television Sets PS ?

A total of 40 brand X television sets and 80 brand Y television sets were purchased for a motel chain. If the price of each brand Y set was twice the price of each brand X set, what percent of the total bill was the price of a brand Y set?
(A) 0.25%
(B) 0.5%
(C) 0.625%
(D) 0.833%
(E) 1.0%

IMO E

price of 40 brand x sets = 40x
price of 80 brand y sets = 80y = 80*2x = 160x
total bill price = 40x+160x = 200x
price of 1 brand y set = 2x

percentage = (2x/200x)*100 = 1.0%

X be the price of brand X. Y be the price of brand Y.

40X is the price of brand X television.
80Y is the price of brand Y television.
Y = 2X
So 160X is the price of brand Y television.
Total price = 200X
So price of one band Y set = 2X/200X =1&#37;
