alex spent 3/7 of his money he gave 1 /4 of the remainder to his sistet he haf $120 left how much money did he in the beginning
Sonbull [250]
Let his total money be x.
He spent (3/7)*x of his money.
He gave 1/4(x-3/7x) to his sister. 
which is : (1/4)*(4/7)*x = (1/7)*x 
Now,
How much money he have in the beginning = 
(3/7)*x+(1/7)*x+120=x
(4/7)*x+120=x
120=x-(4/7)*x
120=(3/7)*x
x=120*7/3 [cross multiplication]
x=280.

So, Alex had $280 in the beginning.

Use the relative row frequencies in the table below to answer the question. Movie Preference Action Drama Science- Fiction Comed
Arte-miy333 [17]
No, I would not predict her favorite category is action.

If you look at the percents for the female categories, action is not the highest. The highest category is Comedy. If you have to make a prediction, it would be best to go with Comedy because it is the highest.
