A collection of a cell phone ring tones usually sells for $18.80, but it is on sale for $10.34. What is the percent discount?
10.34/18.80 = x/100
Cross multiply
18.80x = 1034
Divide by 18.80 on both sides
x = 55
Now, subtract 55 from 100 since you're trying to find the amount discounted
100 - 55
Simplify
45%
And that's your answer :)
