Sure, let's go through the solution step-by-step based on the given scenario to clarify any doubts:
Given Problem:
A computer lab initially has 9 computers. Each day, 5 additional computers are added to the lab. We need to determine the cumulative number of computers added over the span of 4 days and the total number of computers in the lab at the end of this period.
Steps to Solution:
1. Identify Initial Number of Computers:
- Initially, the lab has 9 computers.
2. Determine the Number of Days Computers are Added:
- The time span considered here is 4 days (from Monday to Thursday).
3. Computers Added Each Day:
- Every day, 5 new computers are added to the lab.
4. Calculate the Total Number of Computers Added Over the 4 Days:
- If 5 computers are added each day, then over 4 days, the total number added is [tex]\(5 \text{ computers/day} \times 4 \text{ days} = 20 \text{ computers}\)[/tex].
5. Determine the Total Number of Computers in the Lab After 4 Days:
- Initially, there were 9 computers. After adding 20 more computers over 4 days, the new total will be:
[tex]\[
\text{Initial computers} + \text{Computers added} = 9 + 20 = 29
\][/tex]
By following these steps, we can determine that:
- The cumulative number of computers added over 4 days is 20.
- The total number of computers in the lab at the end of the 4 days is 29.
Thus, the solution to the problem gives us:
- [tex]\( \text{Cumulative computers added} = 20 \)[/tex]
- [tex]\( \text{Total computers in the lab} = 29 \)[/tex]
