How can we find out in such questions the percent increase? like here it is taken as 5% of 20. So how can we assume that?
GIVEN: At a certain company, employees who earn $20.00 per hour will be given an increase of $1.00 per hour. For each of the other employees, either the employee will be given an increase of $1.00 per hour or the employee will be given a percent increase equal to the percent increase that will be given to the employees who earn $20.00 per hour, whichever results in a larger increase for that employee. Which of the following statements are true?
Are you referring to Statement A?
A. An employee who earns less than $20.00 per hour will be given a percent increase that is greater than the percent increase that will be given to the employees who earn $20.00 per hour.
If someone presently earns $20 per hour, a $1 increase represents a 5% increase.
Percent increase = 100(new - old)/oldSince the new wage is $21 per hour, the percent increase = 100(21-20)/20 = 100/20 = 5 (percent)
Let's see what happens if someone presently earns $18 per hour
This person's new age will be $19/hour
In this case, the percent increase = 100(19-18)/18 =100/18 ≈ 5.56 (percent)
Does that help?
