Answer:
After 25 weeks the number of students will be 101.
Step-by-step explanation:
Dr. Harris opened an English Language School in Berlin. He began with 26 students and enrolls 3 new students per week.
Let us assume that after x number of weeks the number of students will be 101.
Hence, 26 + 3x = 101
⇒ 3x = 101 - 26
⇒ 3x = 75
⇒ x = 25
Therefore, after 25 weeks the number of students will be 101. (Answer)
