Sure, let's break this down step-by-step:
1. Initial Information:
- We start with a specific number of computers on Monday, which is 9.
- Each day, a certain number of new computers are added, which is 5.
- We are considering the period from Monday to Thursday, which consists of 4 days.
2. Calculating Total Newly Added Computers:
- Each day, 5 computers are added.
- Over 4 days (Tuesday, Wednesday, Thursday, and Friday), the total number of computers added would be [tex]\(5 \text{ computers/day} \times 4 \text{ days}\)[/tex].
- This gives us a total of 20 new computers added over these 4 days.
3. Calculating the Final Total Number of Computers:
- Initially, we had 9 computers.
- Adding the 20 new computers to the initial 9 computers gives us [tex]\(9 + 20 = 29\)[/tex] computers.
So the number of added computers over 4 days is 20, and the total number of computers at the end of this period is 29.
