Since we know that the probability of extracting a orange candy is greater than 20%, we can rewrite this information as \(\frac{8}{22+x}>0.2\). In other words, there are eight favorable cases, the eight orange candies out of a total number of cases equal to the total number of candies. Now, we just have to substitute x with the provided answers to get that only A and B satisfies the inequality above.

why can't we solve the inequality and get x<28 as the answer?
