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)
