Astore is having a sale on where movies are 15% of their original price. a movie is on sale for $22.10. what is the original price of the movie?

Ok so first off understand what they are saying. there is a movie on sale for $22.10 which is 15 percent of the original price. So now what you do is set up the problem.

22.10 is = 15% of the price

x = 100% of the price (original price)

 15   = 22.10
100        x

now just use cross multiplication.

15x = 22.10 · 100

solve for x.

15x = 2210
15       15

x = 147.33333333 since the 3's go on forever you can simply put it into a fraction 

x = 147  3
             9

whenever there is a repeating number you can put it into a fraction but putting the repeating number over a 9

What are the choices
