To solve the problem of finding the total number of computers in the server room after additional computers were installed, let's follow these steps:
1. Initial Number of Computers:
Start with stating the number of computers initially in the server room. In this scenario, there were initially 9 computers.
2. Additional Computers Installed:
The problem states that 5 more computers were installed each day over a period from Monday to Thursday. That constitutes 4 days in total. To find out the total number of computers installed during this period, we multiply the number of computers installed each day by the number of days:
[tex]\[
5 \text{ computers/day} \times 4 \text{ days} = 20 \text{ computers}
\][/tex]
3. Total Number of Computers:
Finally, we add the number of computers initially in the server room to the total number of computers installed over the 4 days to find the total number of computers.
[tex]\[
9 \text{ initial computers} + 20 \text{ additional computers} = 29 \text{ total computers}
\][/tex]
So, the total number of computers added during this period is 20, and the total number of computers in the server room at the end of the period is 29.
