A system of equations that describes the number of teachers, t, and the number of students, s, that went on the field trip is: s+t=28 and t= s-20
Step-by-step explanation:
Total number of people attended the field trip = 28
Number of students = s
Number of teachers = t
So, the equations will be:
28 of people attended the field trip can be written as:
s+t=28
and The number of teachers on the field trip was 20 less than the number of students. can be written as:
t= s-20
So, the system of equation are: s+t=28 and t=s-20
We can solve these equations to find value of s and t.
