Question is Incomplete, Complete question is given below.
Mrs.Smith teaches junior high school. During a class party in fourth period, she used 4/5 liters of soda for 12 students. If she had a class party in fifth period and used the same serving size, how many liters did she use for 30 students?
Answer:
Mrs. Smith used 2 liters of soda for 30 students.
Step-by-step explanation:
Given:
Number of students = 12
Amount of soda used for 12 students = 4/5 liters
We need to find amount of soda used for 30 students.
For 12 students = 4/5 liters of soda used
For 30 students = the amount of soda used
By Using Unitary Method we get
Amount of soda used = 
Hence Mrs. Smith used 2 liters of soda for 30 students.
4*20%
4*.2=
.8
4-.8=
3.2
The sales price would be $3.20
X+6=3y
y=X/3+2
to graph it you have to find y and x intercept<span>
To find x-intercept , y = 0. Substitute it to x-3y=-6
x - 3(0) = -6
x = -6
First point is located (-6,0)
To find y -intercept, x = 0.Substitute it to x-3y=-6
0 - 3y = -6
-3y = -6
y = 2
second point is located (0, 2)
