Answer :
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
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

whenever there is a repeating number you can put it into a fraction but putting the repeating number over a 9
Answer:
$147.33
Step-by-step explanation:
In order to solve this problem we just have to do a quick reasoning, the problem states that the movies are being sold for the 15% of their original price, so 22.10 represents the 15% of the original price, with this we can just do a rule of thirds to be able to calculate how much is the 100%.
[tex]\frac{15}{100}= \frac{22.1}{x}[/tex]
Now if we just clear the x we can solve the equation for X.
[tex]x=\frac{(22.10)(100)}{15}[/tex]
[tex]x=\frac{2210}{15} \\x=147.33[/tex]
So the original price would be 147.33
