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)

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.
