Giving the following information:
Darcy gave her nail technician a $5.40 tip. The tip was 20% of the cost of the manicure

Cost of the manicure= tip / tip percentage
Cost of the manicure= $27
The percentage of students who spend less than 4 hours a week on screens which reported a grade average below 80 is 50%
Given, we have the report representing children spending time online, on social media or watching T.V, which has there effect on there grades as above or below 80.
By the question we know that the number of students who spends less than 4 hours a week on screen is:
9 + 9
= 18
And among the 18 students there are 9 students whose grade average is below 80.
So the percentage of the students who spends 4 hours a week on screen is:

= 100/2
= 50%
hence 50% students spend less than 4 hours a week on screens.
