Answer:
50 years old
Step-by-step explanation:
Average age of 35 students = 14
Find the total age of the 35 students:
Total age = 14 x 35 = 490
If the teacher's age is included, the average age increases by 1:
average age of 35 students and the teacher = 14 + 1 = 15
Find their total age:
Total age = 36 x 15 = 540
Find the teacher's age:
Teacher's age = 540 - 490 = 50 years old
Answer: The teacher is 50 years old.
