The algorithm dictates that a discount greater than 50% leads to the output "Great deal!" Since a 30% discount is less than 50%, the expected output will be "Wait for a better sale."
The expected output for the algorithm given the input of 30 would be "Wait for a better sale." Since the input is 30, which represents a 30% discount, it is less than 50.
The condition in the algorithm states that if the discount is greater than 50, then the output should be "Great deal!" Else, the output should be "Wait for a better sale."
Because 30% is not greater than 50%, the correct response is to wait for a better discount.
