Mr.Yakima teaches science classes,
with the same number of students in
each class.Of those tudents are 80 sixth graders and 40 are fifth graders.
write an equation to model this situation using the variable n. What does your variable represent?
N is the students in each class, so 3N is the total number of students.
3N=80+40
To write an equation to model this situation, we need a variable to represent the number of students in each class. Let's use the variable 'n' for that.
Since Mr. Yakima has the same number of students in each class, we can set up an equation by adding the number of sixth graders and the number of fifth graders together, and then equating it to the total number of students.
The total number of students in both classes is given as 80 sixth graders and 40 fifth graders. Therefore, the equation can be written as:
80n + 40n = Total number of students
In this equation, 'n' represents the number of students in each class.
