2.) Dr. Harris opened an English
Language School in Berlin. He began with
26 students and enrolls 3 new students per
week. In how many weeks will he have
101 students?

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)
