Answer:

$13.50

Step-by-step explanation:

We can find the total bill here by multiplying $45 by 1.20, where the 0.20 represents the 20% tip:

1.20($45) = $54

Since the four friends agree to split the bill equally, each pays:

$54/4 = $13.50

<h3>What is the average of a group of numbers?</h3>

The average of the group of numbers is the ratio of the sum of all the numbers of the group to the total number of the group.

Lisa is currently taking physics as one of her electives in school.

Her grade at the end of the year is determined by the average of four exams, each worth 100 points.

  • On her first test, she got an 84,
  • On her second, she got a 92,
  • On her third, an 80.

She got exactly 80% in the course. Let she scores x marks in her fourth exam. Thus,

\dfrac{84+92+80+x}{4}=80\\256+x=80\times4\\x=320-256\\x=64

Hence, the score which Lisa should get in her fourth exam of school to get exactly 80% in the course is 64.

Y= 2x+4, because when you plug in x and y you then solve for b and get 4. The 2x is the same because the slope stays the same on parallel lines.
