Matt starts swimming lessons on 5 day . He goes every 10 days . How many lessons will Matt go to in 30 days?
Mnenie [13.5K]

Answer: 3 lessons

Step-by-step explanation:

Matt starts swimming lessons on Day 5.

He then goes to swimming lessons every 10 days. The dates he went on lessons are therefore:

First lesson = Day 5

Second lesson = Day 5 + 10 days = Day 15

Third lesson = Day 15 + 10 days = Day 25

Fourth lesson = Day 25 + 10 days= Day 35

<em>He therefore only went for 3 lessons because the 4th lesson was after Day 30. </em>
